We'd been dating/living together for almost a year, as well as running a business together. We were best friends, business partners, roomates, and lovers.
I walked in on him having sex with my friend in our bed. We'd been on bad terms for a few weeks over a monster fight/disagreement deal. I came home to change on my way to the gym with a friend, and saw a sweater and purse that weren't mine on our couch. I walked into our bedroom, and sure enough, they're curled up in bed naked. I ripped the blankets off, told her to get her skank ass out of my god damn apartment, and I told her if I ever saw her again, I'd kill her.... she had saggy titties and back-rolls. it was gross.
I slapped him across the face, then he grabbed me by my throat and tossed me across the apartment. 2 days later, he beat me up pretty good because I flipped out and yelled at him calling her a cunt-whore, and he didn't appreciate it. I moved out a few days later after filing a police report against him.
He now wants a relationship with her, and she wants nothing to do with one, she pretty much just used him for sex. I got a laugh out of that when I found out. He's also going to court over selling stolen items from his performance car shop, and his business is in the hole about $30k. He's gone downhill the last 4 weeks since I moved out, and my life has been nothing but great so far. Dropping him was the best thing I could have done for myself, and he's getting what he deserves, I'm just sitting back and enjoying the show
