Apparition saidum, if he was married, then I would consider YOU the abuser, he I would just consider an asshole.
I did and do feel bad about that so I don't want to seem like I'm excusing my behaviour but I was young at the time. I certainly don't feel I abused anyone though. I'm the one that has to take pain killers every day because he damaged my leg so bad I have damaged nerves. I see your point but I think that's an unfair statement.
Holy shit. And you waited until HE left YOU? The guy sounds like an absolutely awful brute!
I can't pretend to understand the logic behind that decision. If I were in your unfortunate position right now, I would avoid any remotely romantic relationships for the next couple of years and work on myself. See a therapist for the body issues (both kinds, a mental health therapist for the mental anguish and a physiotherapist for the physical damage). Start lifting weights to build up the muscles around the weakened area (that's what I did when I damaged my ACL in sports, it works), and some of the pain will go away and the likelihood of future injury would decrease.
And finally, when you do end up in a romantic relationship again, screen potential partners for size. Try not to fall for someone who outweighs you by a large margin, because people who end up in 1 abusive relationship sometimes are more prone to ending up repeating the cycle. At least if the other guy is your size, you'll have a chance to defend yourself and won't end up dead if it happens again.
Domestic abuse is something that doesn't get talked about a lot in gay relationships, but it happens.
I wrestle with my boyfriend (for sexual purposes lol), and it can get very competitive, but I know he'd never assault me. If he did, he'd be out the door so fast.
