30 In-Laws Share The Exact Moment They Understood That Their Relative’s Marriage Wouldn’t Last

Probably when he punched my daughter square in the face in front of our entire extended family.

Was the sister-in-law. The first time she and I went somewhere together she said, "Your brother's kind of been pissing 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.

Sister-in-law here. I'd say it was when he pushed my sister into a thornbush over a petty argument the day after they got married.

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 4 days after being legally married sis calls me crying an screaming that newly wed 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 the .38 off my hip yell at him to drop the knife, he spins around I blast a round into his left thigh he's screaming blood everywhere I call 911. Police, paramedics, EVERYONE shows up.
Turns out that my sister and him had a dispute about her 'guy friend' at work she's always texting. Sister gets mad stabs husband with knife husband somehow wrestles knife away from my lunatic sister tries to calm the situation and I bust in the door and shoot the poor bastard. Great guy didn't press charges we got it settled all nice like 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.

The moment someone told me they were having a child to save their marriage.

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 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 anyway, she bailed him out because she missed him.

When the actual father of their youngest child came forward to demand a paternity test... he won.
DNA test on older child also showed no genetic match. No surprises here.

When she was kissing another guy in one of the wedding photos.

It didn't go over well.

When my sister told me he tearfully confessed to her on their wedding night that he had murdered and buried someone in the desert. After she urged him to turn himself in, he told her he was only joking.

At my wife's sister's wedding myself, my wife and my mother in law had a betting pool with the groom's two brothers on how long the marriage would last. Lowest guess was 13 months by my mother-in-law. 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.

When she tried to tell us that cooking m*th in a self-made underground complex beneath his shed in the backyard made him a "self-starting entrepreneur." And this guy was not Walter White, genius chemist from New Mexico. This was Ricky from Alabama who got his GED at 24.

Sister here. Thankfully this marriage never happened; the relationship ended shortly after the proposal, but I knew my brother's fiancee was a gold digger within an hour of first talking to her. My brother makes a ton of money, and I'm pretty sure that 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 kinda shocked that my brother managed to ignore them all. When I asked her what she liked about my brother, she said, "Uhhhhhh.... well, he has a really high paying job and he's good at fixing things, so he's pretty useful, hahaha!!" She also kept talking about how she was taking time off from medical school, and it became really 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 100% 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.

Edit: Some people are commenting saying that they wish that they were close to their siblings, so I just want to clarify: I'm not close to my brother. We've never been close. But he *is* my brother, so I've got his back. So don't be sad if you're not close to your siblings. They will probably have your back when the time comes no matter what.

When he brought his wife and his girlfriend to Thanksgiving brunch.

Before she ever got married, when she told us she was going to help him get over his substance abuse problem.

When they decided to get married when he was in boot camp.... Through mail. They married the week he got out. And divorced 4 months later...

Sister-in-law here.

I was 7 years old when my sister's new boyfriend walked into our house, took one look at the fish tank and asked, "how do they breathe?" He was at least 20 years old at the time.

They stayed together 8 years, 2 of those married, before divorcing. He's a meth addict, and my sister is remarried with a beautiful family now.

I was the brother in law.

She would call me all the time when I lived in Maryland to complain about my brother. When I lost my job and moved back home she was constantly pulling me aside to have small conversations.

When we went out one time she sat down next to me and asked me "Which guy in the bar I would be okay with her cheating on my brother with?"

When he caught her [sleeping with] a coworker.... on their anniversary.

When he refused to go somewhere with her because it was outdoors and he doesn't walk on grass or dirt.

When he told me she didn't like gynecologists or birth control because they caused cancer, but it's fine because she was pregnant anyway. Flabbergasted, I asked why? And he said her mom wants grandkids.

Jesus I can't wait till he wakes up.
