We need some more crazy dude stories here, so this is mine:
Started dating this guy when I was 16, and he was 18. We worked together, things were great for a long time. I was pretty religious as a teenager and so we never had sex, but messed around a lot. He was my best friend, and we had a lot of fun together. It was frustrating because I had a very eccentric style and taste in music, and he didn't like my style or music so he slowly got me to conform to what he wanted in a girl. He also discreetly fat shamed me, but said it was all for my "health". I was not fat, but he preferred very athletic toned girls.
I wanted to break up for a long time, but he had a lot of family issues and so I felt bad. Broke up once (because he wanted to read my private journal and I told him no), but he convinced me to date him again within the week. He was in ROTC, and after about a year and a half of us dating, he had to go to a month long training. We could only write letters, and I wrote him about every other day. But I realized while he was gone that I was happier without him. I will confess here that I did "cheat" on him while he was away with a guy who was across the world on messenger. Mostly just talking about sexual things and flirting, but I realize it was just not right to do that to him. He gets back from training, and a week later I have to leave for 3 weeks for a family trip to Montana. So I'm on my way to Montana and we had stopped in Utah for sight seeing, and he will not stop texting me. I understand he was happy to be communicating again, but he kept getting mad that I wasn't replying fast enough (within minutes), so I finally broke up with him. We hung out a few times when I got back, but it was weird and so I stopped seeing him. He was still all in love with me, and I confessed to the online cheating to try to get him to go away.
So he starts freaking out at me, messaging me a bunch of horrible things about me. My dad saw it due to a computer glitch, and told him off. He started talking to people at our church, and told them how horrible I am, but luckily everyone stood up for me and told him they wouldn't tolerate his behavior. He typed up every letter I wrote to him while at his training and posted it on Facebook as proof I used to love him, which I learned from friends because I had him blocked. One of my friends older brothers threatened him and made him take them down.
He saw me driving to a friends bb game one day and followed me and harassed me in the game, but eventually left. I go to the parking lot after the game and he is by my car SHIRTLESS trying to show me what I am "missing out on". He then tries to stop me from leaving by holding my car door open and trying to kiss me saying that I will love him again if I do. I kick him as hard as possible in the stomach and he finally leaves.
A couple months later he texts me and tries to get me to come over to his house and have sex, I tell him no. And he says "I just wanted you to come over so I could call you a slut and throw condoms at you".
Eventually he backed off, and I haven't heard from him in forever. But theres your dude crazy for you!
