Is he becoming a safety concern?

My boyfriend has a history of being controlling and verbally abusive. But he said he would work on things. He has been better but I notice little things that make me wonder if he really will. Last night we had sex and he was choking me. We’ve done it before but this time it felt… different…He did it a lot more than he usually does, a little harder than usual, and at one point I genuinely was going to faint. I thought maybe it was an accident maybe but at the same time, we’ve been doing this for 2 years and he’s never been that way about it. He’s also done that with past girlfriends and has even made one pass out before so I feel like he should be able to recognize the signs by now?

Another reason that it’s making me cautious is because I noticed he’s increasingly uncomfortable with my friendships. For example, after we were having sex, I was texting someone I know from high school (I’m 23) and he was literally just telling me about a video game. My boyfriend was reading over my shoulder and was like “who is that?” And I briefly explained (I’ve explained him before so I didn’t think I needed to again) and he just stared at me funny. When I asked he said I never told him about him so he was waiting for an answer. He told me he “doesn’t understand why I need to talk to someone I went to school with”. I also had an instance where my manager was sexually harassing me and he blamed me and told me that I should just get a stay at home job bc he doesn’t trust me
