They say you should always listen to your gut, but love can make you blind sometimes. Sadly for these couples, they really should've listened to their family before marrying into these crazy relationships, and all their family could say is, "We told you so."
After Their Sister-In-Law Spilled Her Secrets, It Was All Over For Her

“I was the sister-in-law. The first time she and I went somewhere together she said, ‘Your brother’s kind of been ticking me off lately. Do you think I should cheat on him again?’ To which I asked if he knew about the others and she informed me he did not. I told her, ‘He will now.’ They divorced shortly after.”
He Brought Out The Absolute Worst In Their Sister

“I knew the first day I met him that he was a tool.
My sister dated a guy for years. It was rocky and not healthy in any way, but it was by far the best relationship she’d ever been in. I was coming around to the possibility that he might become my brother-in-law.
She dumped him. Two weeks later, she moved in with toolbox guy who was still very much the junkie she had been trying to stop being herself. He told my Mormon parents stories about wandering around the highway on some hard stuff and being cursed in Africa. He had an explosive temper, no prospects or a desire for prospects, and brought out the worst in her. They got married eight months later.
They stayed married for a decade. She stopped doing illegal substances (but still drinks, although only occasionally to excess), finished school, went to nursing school and got her master’s. He kept a job for a few months once. When he fell off the wagon, he stole and sold a bunch of her stuff and then broke into my parents’ place to steal and sell their stuff. They divorced after this, but he kept stalking her for a while, mainly looking for fix money. I haven’t heard anything recently, probably because she has a boyfriend who is interested in being a better person and truly cares about her and her well being.”
They Thought They Were Helping Their Sister From Their Crazy Brother-In-Law But Actually

“A few months back, my sister married a super nice guy. They hadn’t been dating that long, like right under a year. They were super happy and looked like a perfect marriage. So the perfect happy couple got married, and literally four days after being legally married, my sister calls me crying and screaming that newlywed husband is attacking her. As the heroic little brother, I rush over to her place as fast as I can burst inside to see him and her having a stand-off in the living room. He’s bleeding, holding a knife and she’s screaming bloody murder. So I think my sister is about to be stabbed to death, so I grab my weapon off my hip, yell at him to drop the knife, and he spins around. I blast a round into his left thigh and he’s screaming, blood is everywhere, so I call 911. Police, paramedics, EVERYONE shows up. Turns out that my sister and her husband had a dispute about her ‘guy friend’ at work she’s always texting. Sister gets mad and stabs her husband with the knife. Her husband somehow wrestles the knife away from my lunatic sister, tries to calm the situation, and I end up busting through the door and shoot the poor guy. A great guy. He didn’t press charges we got it settled. I paid his medical bills and they divorced. I gained a new best friend with a bullet scar, and I don’t really talk to my sister.”
This Compulsive Lying Wife Ruined Their Brother’s Life

“My older brother married a woman who was a compulsive liar. Like lied about everything, and was crazy.
She said she was raised on a vineyard, but no one in her family drank, they made drinks for the money.
She said she was raised on a no-kill cattle ranch.
She said she had a horse that she would routinely let inside the house when her parents were asleep.
She said her grandpa was a lawyer and mayor in Georgia.
My wife and I had them over for dinner while my wife was six-months pregnant, and my sister-in-law said she loved the smell of baby poop.
She was married four times prior, twice to one of the guys (she was 33).
She said she started a cleaning company with an ex-husband, and that the ex-husband was going to give her the company because her and my brother were in a tough spot, financially. Then the ex-husband supposedly reneged on it.
Met my brother in an AA meeting while they were both living at a homeless shelter.
Got them both kicked out of the homeless shelter for breaking rules.
Told my brother she was pregnant, and at the first ultrasound, the doctor heard three heartbeats.
Told my brother that she was fired for being pregnant.
Told my brother that the day before she was supposed to go to the doctor that she had a miscarriage.
That’s just some of the stuff. I found and contacted one of her ex-husbands. She grew up just outside of Chicago, and she has some disease where she can not carry a pregnancy.
When I asked my brother (a few days after we had them over) how full of crap she was, he gave me a half-hearted answer, then cut all contact with me.
He had depression and anxiety since high school, and two months after the pregnancy, he hung himself in his garage.
At least that’s the story we heard; the police report I got says he was laying on the ground when the police got there, and there was no autopsy because they were living in the middle of nowhere Ohio when it happened. Her story of what happened that day has changed a few times.
I believe that he killed himself. I also believe that she definitely drove him there. I don’t think she murdered him outright. He had depression. The circumstances that led them to the middle of nowhere Ohio where he killed himself are depressing too.
Also, since hindsight is perfect, there were signs that he was seriously depressed before the events that ended up with him in Ohio.
My mother ran into her a few months ago, and apparently, she was in a coma for the last two years. Which is weird because my wife and I ran into her nine months ago and she was super excited because she was living with some new church friends.”
These Childish Temper Tantrums Weren’t Going To Fly With This Family

“Sister-in-law here and I knew when they announced their engagement. I met her before, and she had seemed a little high-strung, a little immature, but seemed like an ok person, and she and my brother hadn’t been dating very long. I hadn’t seen her in a setting where others were supposed to be the center of attention.
We were at a close family friend’s rehearsal dinner. Brother brought his girlfriend as his date. The groom’s family had picked this nice Italian restaurant that had needed to be reserved months in advance. Brother’s girlfriend tried to get everyone to change venues because she ‘felt like Chinese food.’ When she didn’t get her way, she showed up to the restaurant pouting, arms folded, lower lip out. She snarled at the waiter that he had better have Pepsi or she was ‘going to mess stuff up.’ She ordered the most expensive item on the menu and then refused to eat it. As in, it sat there untouched while she scarfed down her fifth Pepsi. Then in a moment of silence from the rest of the table, she slid her engagement ring on her hand under the table lifted it up and screamed, ‘I’m engaged!!’ At the top of her lungs and said, ‘I bet you all are sorry now you wouldn’t let me have Chinese on my engagement night.’ My date convinced her to let us take her out for desserts at a little bakery up the street with the goal of getting her out of the restaurant hoping everyone else could give attention to the actual bride and groom of the weekend. As we were leaving, brother’s now fiancĂ©e turned to my parents, her future in-laws, and said, ‘Don’t think I don’t know you all don’t like me.’
She got up to similar shenanigans on every family holiday, their wedding, and their divorce.”
They Could See This Relationship Burn From Miles Away

“It hasn’t crashed yet, but much like the town of Centralia, Penn., near where they live, it is slowly burning to bits underneath.
She was in an abusive, cheating relationship for three years, and they finally split when she got knocked up with his kid. I’m not sure if he ended it with her (on account of him having three other kids with other exes) or if she just realized this guy with no prospects couldn’t be a father.
Cut to two years later, she has a beautiful son, finished her nursing degree, and is finally making decent money with a stable job. She decides to get back in the dating scene, but is 28 and has put on some weight.
She moves in with the first guy she goes on a date with, two months after they meet. He is nice enough, has a couple kids. But she left her beautiful apartment to go live in a trailer with him.
He has no prospects, is 15 years older than her, and barely pulls in enough income to live in the trailer. I’m just waiting for the day she wakes up and realizes she can do so much better. She doesn’t deserve a guy with a drinking problem who makes half of what she does, leaving her to support his kids, as well as her own. She was just beginning to pull out of debt and the cycle of substance abuse in her family, too.”
“We Both Know She’s Just Going To Have Another One In A Few Months”

“My cousin got pregnant at 16 and married the father at 17. They split up eight months later and divorced on their one year anniversary. She proposed to her next boyfriend a few months after that but accused him of cheating on her and broke off the engagement less than two weeks later. She then met and married another man a few years later at age 21, remained married to him for three years, and then filed for divorce, stating that ‘She wanted to divorce him before she did something she would regret.’
A few weeks after that she was pregnant with the child of her fourth man/significant other/beau (at this point it doesn’t really matter what you call them). She married him at 26 years old. I skipped the wedding. My mother called me after the wedding, angry that I hadn’t bothered to show. My response only made her madder:
‘Mom, we both know she’s just going to have another one in a few months.'”
This Sister-In-Law Hopes No One Has To Deal With This Selfishly, Insane Woman

“Sister-in-law here:
The red flags were many, but the biggest one for me was the day I first met her. She was younger than me (my brother is 10 years my senior), and she asked if I thought he’d get a credit card with her. She had a laundry list of things she wanted. I did the math, and they were in excess of $10,000.
If there is a runnerup flag, it’s the day my dad died about two months after I met her (and four months of my brother and her began dating). She went to her boss and started a fight, losing her job. She demanded to ride in the family car (because a girlfriend of four months counts apparently). She told my brother she was pregnant that same day (she had told me at our first meeting that she knew she could not get pregnant at all). They were engaged the day of the funeral. She also tried to walk off with some things my very upset mother gave her (I put them back) and called me the b-word twice. I was in my early-20s and had just lost my father. Such a nice woman.
They just divorced this year. She has some new boy toy, and I hope someone stops her before she sucks him dry too.”
Her Reality Star Antics Set Off Red Flags For This Cousin-In-Law

“My cousin married his longtime girlfriend. She’s always been slightly ditzy and such, but she’s a promoter for a bar, so we figured it was the gig, but lo and behold during the ceremony, she wouldn’t look at her soon to be husband, only at the camera crew, and stopped the vows so they could ‘get a good picture of her life-changing moment.’
Bonus: when the pastor asked if [she] would take [him] to be her lawfully wedded husband, there was a drawn out 10-second pause where she ‘pretended’ to think, made a face, and finally said ‘uhhhh YES’ with a hair flip and all.
Lord help the poor guy when his wife likes to check her look in pictures more than looking at her husband during the vows.”
“That Girl Is Going To Be Trouble” Said This Father-In-Law

pathdoc/Shutterstock
“My ex-sister-in-law.
Dad knew after my brother brought her home to introduce her. They left to do whatever. Dad was very quiet for a moment, then said gravely, ‘That girl is going to be trouble.’
And he was right. So dang right.
Some of the million things she did: She started out by hating my mother right off the bat, but for no good reason. Now, Mom wasn’t perfect by a long shot, but she was not a bad person by any stretch (both of her sons-in-law wept at her funeral and still miss her if that tells you anything). She even tried to get Mom committed. She turned my brother – who was already a lying narcissist – into a monster. She refused to let our parents have a relationship with their children, which is as much his fault as hers. There is so much more, but I think you get the point.
Karma bit brother in the butt for inflicting her on us, though – they’ve been divorced for about seven or eight years now, and she took him to court a couple of years ago to increase her alimony. She doesn’t need alimony – she has a trust fund and her dad is wealthy. It’s pure spite. She’s just that nasty of a person. And she won the petition, too! I was amazed.”
It’s Bad When Both Sides Of The Family Start Making Bets On Your Marriage

Antonio Guillem/Shutterstock
“At my wife’s sister’s wedding, my wife, my mother-in-law, and I had a betting pool with the groom’s two brothers on how long the marriage would last. Lowest guess was 13 months by the mother-in-law; the marriage lasted 10.
They started marriage counseling while engaged. The honeymoon involved separate vacations. Thank Christ there were no kids.
Her second marriage was even worse.”
They Were Called A “Negative Nancy” But They Were Just Seeing The Truth

“Ah, I thought they’d never make it down the aisle, but sadly they did. Some things that tipped me off:
He wouldn’t fool around with her for two years for reasons that are totally-not-related-to-the-fact that-he’s-attracted-to-men-instead.
He treats women like crap, including his fiancee.
It’s his way or the highway ALL THE TIME. Like ‘either we stay at this hotel or we break up.’
He put them into debt equal to about two years of their COMBINED salaries.
He bought stuff for himself all the time but wouldn’t buy her a wedding ring.
He had very specific ideas of what the wedding should look like, and wouldn’t let her have any input.
And yet I was considered a negative Nancy for thinking they wouldn’t work out.”
Their Domestic Disputes Are Leading Them To A Path Of Destruction

“When I met my sister’s now husband then boyfriend, he was dragging her by her hair to the car because she left the house without telling him and he thought she was with a guy. She was having lunch with me.
The second time I met him, they had an argument at my parents’ house in my room while I was in it. He kicked me out and shut the door. I had my ear on the door, and I heard a muffled noise, then loud gasping. I was banging on the door shouting and begging him to let me in. Turns out he was pushing my pillow on her face.
I made the mistake of moving in with them to help my sister with the baby because yes they thought having a baby was a good idea. They had an argument, and he lifted her up like something out of WWE and let her drop to the floor. I called the cops, she told them whoever called was a liar. They took him in anyways, and she bailed him out because she missed him.”
They Had To Rescue Their Sister After This Guy’s Meltdown

“My sister met a guy from the Air Force on League of Legends who lived a couple states away. She moved there to live with him; I was under the impression they were only dating. A while later, I found out they got married without telling anyone, including our parents. I found out after they had been married for a year, and my parents found out a couple months before me and neglected to tell me for some reason.
I knew it was done when her husband turned 21. They went out for his birthday and he drank his tail off. He was messed up when he and my sister got back to their home, so she drew a bath for him so he could try to get a grip. He ended up going insane; he threw a butcher knife at her as she was running to her car. For some reason, the dude thought he was the devil incarnate and had to be manhandled by the police.
The state pressed charges against him, but my sister did not want to. Despite the fact he was arrested, he did not lose his job in the military. He was clearly abusive and my sister was a step away from suffering Stockholm syndrome. My brother, mom, and I ended up driving 12 hours away to rescue her a couple days before Christmas (they knew we were coming under the intent of bringing my sister home). Definitely the weirdest Christmas day of my life.
My sister is now dating a down to Earth guy who I approve of, and I’m pretty sure she’s officially divorced from the other dude.”
They Knew It Was Over Once He Went Absolutely Nuts

“It was Christmas-time, and my sister and her husband were buying gifts at a mall. They stopped at a little cart selling spiced nuts. They bought some. They also each got to have a sample one. She was holding both his and hers, and he asked her to hold some stuff for him and to free up her hand, without really thinking, she ate his sample nut. Even though they had just bought a package of them, he lost his mind about it and wouldn’t speak to her for the rest of the day because she ate his sample. His anger was always disproportionate like that. I knew it couldn’t last much longer at that point.”
These Facebook Pictures Revealed Too Much About Her Horrid Personality

ESB Professional/Shutterstock
“This was my in-law’s cousin’s ex. Her Facebook was literally nothing but booty shorts and shoes. Not that there’s anything wrong with showing off your nice body and things that you worked hard for. But this girl worked for nothing and had no redeemable qualities about her.
But, she wasn’t the only one to blame. He had broken up with a nice girl. Rumors were that he hit her, but he said she was bipolar. Whatever. After they broke up, he met her. His family told him to watch out for her, but he told them to butt out. They did, all while knowing inside it wouldn’t work, but they were still hoping they were wrong.
He’s smitten with her and goes on bragging about how good of a husband he’s going to be and how you should treat your wife, basically letting her have everything she wants no matter what. Family and friends saw this and were all like, ‘What the heck?’ and he began blocking anyone who tried to tell him he needed to think about it.
She changes her appearance (no more tight, revealing clothes) and tones down her Facebook and she got the ring and the ability to update her status on Facebook.
Shortly after, they got pregnant and her mom moved in. So it’s her and her mom ruling the house. She began showing her horns when and started mass uninviting his family from her baby shower. The baby comes around, and she’s having him tell his mom she can’t see the baby. His mom beats some sense into him, and he finally grows a spine and puts his foot down.
So she moves out and takes everything with her. He doesn’t even get a couch to sleep on. They divorced recently and they’re both still the same people. There’s a lot more stupidity that happened during the time between the separating and divorce, but we all saw it coming.”
This Sister-In-Law And Her Brother Dodged A Bullet With This Gold Digger

pathdoc/Shutterstock
“Sister here. Thankfully this marriage never happened; the relationship ended shortly after the proposal, but I knew my brother’s fiancĂ©e was a gold digger within an hour of first talking to her.
My brother makes a ton of money, and I’m pretty sure she latched onto him because she wanted him to pay her credit card and student loan debts. There were so many red flags I’m shocked that my brother managed to ignore them all. When I asked her what she liked about my brother, she said, ‘Uh, well, he has a really high paying job and he’s good at fixing things, so he’s pretty useful, haha!’ She also kept talking about how she was taking time off from medical school, and it became obvious to me that she was trying to use the marriage as a way to drop out of medical school completely and live off of my brother’s money.
She also spent the entire time talking about designer bags and dresses, and how she’d been taking out loans to buy herself thousands of dollars’ worth of bags. I hung out with her for a few hours, and by the end of it, I was sure she didn’t like him as a person at all. I ended up telling my mom, who told my brother, and he confronted her, and she admitted to all of it and they broke up.”
