My boyfriend thinks I should talk about what's bothering me to a friend group I want to cut off

I'm at a point where I need to cut out certain people from my life. I've been hanging out with people who know both my exes and I've been open about the abuse they both put me through even though it's beyond my comfort zone to talk about those dark times. What I got from the people my exes and I know is statements about my experience not being so bad and that maybe I'm not seeing the good parts,no heart feelings etc ( people telling me how to feel about MY experiences is a trigger of mine ) Besides invalidating the abuse ,they also share what's going on in their lives in front of me or directly to me even though I have never asked and told them I don't want to hear anything about them. It drives me crazy to think they share information about my life with 2 of my worst abusers in a casual manner like they share with me about them. Any time I hear a story about one of them my mood shifts immediately and my night out with these people is ruined. The last straw was a few weeks back when they invited me to hang out in their house and there was music playing for about an hour already and I was dancing to it and having a good time and then one track comes up and I keep dancing and I hear them be like "oh this is ABUSER NUMBER ONE's track right?" I froze like a statue and my stomach turned realizing I was unknowingly dancing to a track produced by this pig. I think that none of these people respect me. Yes they like me and invite me to gatherings etc but I don't consider them my friends. In the past when I was open with friends about what is bothering me I was met with mockery,irony ,gaslighting, lies and nothing would ever get resolved or get better until I would have to block them and go no contact. Now I'm in between worlds. I want to just cut them out without explanation since I was already honest about the abuse and they kept acting the same but I also have changed as a person and don't really go no contact with people anymore. So I would like some suggestions ,what would you guys do in touch were me ?
