Dog is unwell, gets taken to vet. Has to have surgery to remove something from stomach. Lacy underwear is removed, and shown to the woman owner of what it ate. Owner realises they are not hers. Husband was cheating, and the dog ate the mistresses undies. Somuch for mans best friend.

I found a travel blog from a girl that had photos of my boyfriend in bed and details about their time together. The blog also mentioned that they were long time travel friends that had met up in various countries. I had never heard of this girl during our 7 year relationship.

I am a divorce lawyer - I have heard it all. One particularly excruciating story was a woman who discovered her husband’s 8-year long-distance affair when he left his email open on his computer. She read through 8 years of their emails, photos and videos (some explicit) and it took her about 4 hours to get through it all. She was crushed.

A quite famous Norwegian podcaster and radio host had a stroke. While lying in the hospital, she received a text from her husband meant for another woman. She then found out he was having an affair, even seeing his sidepiece while she was recovering in hospital.
Somehow they stayed together for many years after, and she talked about it in detail in her podcast. He admitted to everything and owned up to it, but it's still just unfathomable to me. They even had kids at that point, but he chose to hang out with his mistress rather than bringing the kids to see their sick mom. Disgusting.

Happened like 20 years ago with the sister of a good friend.
She cheated on him with the same guy he was cheating on her. He is openly gay now. But what are the odds?

I found out my now ex-husband cheated on me on, of all days, my birthday. I had gone out of town to spend the weekend with my sister and nephew, and the plan was we were going to go out to my favorite restaurant to celebrate on Monday after he got home from work. I was just lounging around, playing on my tablet, waiting for him, and an email notification popped up. The dummy forgot he had linked up his email on my tablet as well, and I, totally unsuspecting, not trying to snoop or anything was just thinking, "Oh, an email!" So I opened it, and there it was... It was from some girl he met up with from Craigslist talking about how much fun she had and could they get together again.
I called my BFF, who immediately came over and helped me pack as much as we could carry, and I left that night. I just texted, "I saw the emails, I know what you did."
But as they say, "Hell hath no fury like a woman scorned." Ex-husband was an immigrant from a 3rd world country. He was on a visa, and we hadn't yet started the paperwork for his citizenship. As soon as the divorce was finalized, I may have anonymously notified his job that his visa was now invalid, and he was working illegally. And then I may have anonymously notified ICE that he was here illegally and trying to work illegally. He was deported.

Got a text from a buddy of mines gf. They had had one of his old classmates passing thru and put her up for the night. His gf goes to bed and he and the classmate stay up getting drunk. His house has motion sensors. Gf wakes up cuz she keeps hearing "motion detected at the back door... Motion detected at the back door..". Over and over again. She goes to investigate and it was my buddy setting it off while he was plowing his old classmate. I felt terrible for her but have to admit I get a chuckle out of it now.

My then-gf was cheating on me, I found out, and took her out to this steakhouse in Chapel Hill she was begging me to take her. I let her order whatever she wanted, and she racked up a $389.00 bill. I told her I was going to the bathroom, but instead walked right out. I did tip the waiter on the way out and informed him that she was paying the bill. About 15 minutes into my return to the barracks at Ft. Bragg, my phone blew up with calls and nasty texts. I answered the 7th call and told her the guy she was sleeping with would be more than happy to cover the bill for her and pick her up (Chapel Hill was a good 2 1/2 hrs away from where she lived), then I hung up and blocked her. Getting cheated on sucked, but I dumped her before I did something stupid like propose to her - and I got a free steak out of it. I never slept so well, lol.

While my mom was in the hospital, I went back home to get my baby because I had rushed out of the house quickly in a panic and left him with his dad (my husband) but knew he would be waking soon to eat (he was breastfed). Husband was asleep but I noticed a Snapchat notification of his phone, I was already in a 'don't care' mood so I checked it & some girl had sent him a full frontal spicy pic. I screenshotted it and sent it to myself from his phone so he’d know I saw it.

That would be one of my old bosses. Married, with three boys under eleven. Owned and ran his own business. For years, every Monday night he would see a lady of negotiable affection. Fool filmed his visits and saved it onto a thumb drive, which he didn't secure. His oldest boys came across it and watched their old man getting down with a dom. He lost everything.

Wife of 13 yrs. I only knew about two men, suspected another, turns out she sent an entire list of the men she was sleeping with to a friend. Bragging, I guess.
She said once "I didn't know it was wrong, no one ever told me".
We were raised Mormon...

He kept hanging out with a female "friend" who was obviously too close for comfort. We were long distant at the time due to the pandemic. It got to a point where I'd get one text maybe every couple hours because he was hanging out with her. He kept saying they were just friends.
Until I saw a video on his story after going to the cinema with her, and she was literally twerking in his face in a empty cinema screen, and whilst he wasn't touching her or anything, he was giggling behind the camera. I messaged him, blew up, he denied and kept saying it wasn't him but his guy friend and he was sitting next to him. Yeah, right. I dumped him, and he insisted they were just friends and called me crazy and insecure. They literally started dating a couple of days after. I blocked him but found out through mutual friends that for 6 months that she rinsed him for all his money and put him into loads of debt as he paid for expensive dinners and gifts, then broke up with him when the money well dried up and that he had to move back in with his mother. He tried crawling back, but I never replied.

My wife's cousin has a GF who was a pen pal with some prison inmate.
One day apparently the prison guy got released. The gf insisted that he stayed with them for a few days because he "had no where to go". The cousin was a push over and didn't say no, even though it was HIS house, his name on the deed, and the gf was just living in it.
The prison guy came, the gf insisted that he slept in THEIR bedroom with her while the cousin slept in the guest room. "Just so he doesn't feel unwelcomed". Then the prison guy never moved out of that room and so the gf just slept in there with him, and the cousin just continued sleeping in the guest room.
Again, this was the cousin's own house. And he was such a push over that he let some random guy move in and basically sleep with his gf.
True yet weirdest story I've ever known personally. The extended family tried to talk sense into him, but he refused to listen. We all did a collective head scratch on this one.

It’s funny coz it happened exactly 18 years ago. I had a best friend that lived on my same block. We went to school and high school together. We also went together to college but I dropped out and started in a different college after the first year. We used to play video games and hang out almost all the time. He was like family. I had a girlfriend back then and was my first serious romantic relationship. We had been together for a year but we were having fights and the relationship was becoming toxic. On my bd day I was at class and decided to text her to check if she wanted to meet. I got no answers. I also texted a cousin but he was busy and texted my best friend but he didn’t answer either. I tried calling and nothing.
I’m a pretty chill person so I just decided to rent some movies, I bought some snacks and was gonna spend the evening chillin by myself at home. We all lived in the same neighborhood and as I was crossing the street to enter my building I saw my friend’s car passing by with my girlfriend on the copilot seat. They were ignoring me the whole day and spent the day together, during my bd.
It was actually pretty bad for my mental health since I didn’t expect my best friend to do something like that with my first love. She also messed up of course. They tried to get out of the car but I just stormed into my building. The first thing she texted me was “please don’t be dramatic” and my friend said they were doing a cake for me LMAO it was a lie of course. I ended up going to a therapist.

Found out my ex had been “working late” by seeing his car in the parking lot of a restaurant while I was on a date with my friend’s boyfriend… who was also “working late.” They were at the same table, sitting together, holding hands. Two relationships ended over one plate of nachos.

Wife spent every night "gaming" with her male bestie. The plot twist landed when her husband silently handed her a screenshot from said bestie: "Babe, your hubby seems to buy it. He's so gullible. Love you." Turned out, "hubby" had been using her fingerprint to access her phone... and had been posing as her to chat with her best friend for a long while.

Ugh, my friend's first wife. What a circus. Couple of my favorite incidents:
--we drop my friend off at about 3am from a bachelor party, and got to witness the classic "dude clutching his clothes and jumping out the window" as we drove away.
--wife was at her best friend's house, best friend's pot guy comes by, best friend leaves the wife and pot guy alone for (from what I have been told) literally 3 minutes as she finishes her makeup...she hears THUMP THUMP THUMP and comes in, pot guy has wife bent over the couch and she's screaming "PUT A BABY IN ME". This was the first time wife met pot guy.
She'd also make him breathe into her interlock device in the morning so she could go to work. Real glad that is not a part of my life anymore.

My parents divorced when I was 16, 3 months later my dad called me from the hospital as he had a new kid. Now I’m no mathmagician, but I THINK he may have been sleeping before the divorce!
