A boyfriend I had junior year of high school (I'm gay) not really sure if this counts, but..

Had just moved to the state and actually met him the next day on Tinder. Met up during lunch and he was drop-dead gorgeous. Pretty much one of his first questions was if I party and do drugs or whatever, which should have been a warning sign. But I don't really care that much for I already smoked weed and didn't think it'd be much of a problem. So fast forward to one night I sneak over to his house. He took xanax or something before I got there. When I arrived, he was extremely sexual but then started punching me in the face and being super rough. I busted my nose pretty bad and I started crying. He instantly got out his first aid kit, acting like it was all over and went all care-giving on me (he HAD his CNA, and was remarkable at medical stuff. Lost it after he got a DUI and had molly, cocaine and Xanax on him).

So this pretty much led me to thinking he was still a good guy and just had a fuck up. After all, he comforted me while I had no friends since I just moved and he was all I had. Fast forward to a Saturday night and he invites me over to this dudes apartment who was pretty much the drug lord of the whole city (didn't know this at the time). My boyfriend never told him I was coming and just told me to walk in. I walked in. As soon as I did I was greeted with a stock of a rifle to the face and guns pointed to me asking who I was. Things like this continued to happen and I don't want to get into a lot of details unless this actually gets noticed, but we ended up staying together for another 5 months and it was absolutely brutal. Never again.
