I (17F) literally cant communicate with my (18M) boyfriend. We dated once before in the past for a year and a half and it was extremely toxic - i won’t even get into that but trust me when I say it was really bad. About a year later, I’m now dating him again and we’ve been together for 6 months and since these are the only two proper relationships I ever had - both with him, I find it hard to let go of the stuff he did to me in the past. He used to have this best friend (gonna call him Jack for the sake of explaining this) who was a complete outright scrote. I met him a couple times with my boyfriend and the whole time all Jack would talk about was women in a sexual way and how he liked getting girls and objectifying girls etc etc to which my boyfriend would laugh at. I didn’t know any better at the time but now that I look back at this it makes me feel like it might make my boyfriend have similar qualities to him - even if he’s not as explicit about them - if he willingly chose to be best friends with someone like that. Jack moved out of where we live to a different country around a bit over 2 years ago and now my boyfriend has new a new friend group. He still stays in contact with Jack and calls him his “best friend” because he says no ones been there for him the way Jack has or something like that but whenever I heard them texting it’s about Jack talking about having sex with girls where he lives. Around 3 or 4 months ago, my boyfriend was showing me a text between him and Jack from the past and he scrolled up a bit accidentally and there was a photo of a nude lady and my boyfriend saying wow she’s so fuckable id fuck her til she cant walk and Jack agreeing to that. I was beyond disgusted. It made me have flashbacks to our past relationship and I told him I wanted to break up with him but he convinced me to stay because those texts were old (they were from last time we were dating) and he said he’s not immature like that anymore. Now, because of how our last relationship was I feel like my boyfriend surrounds himself with people like Jack for friend choices. I don’t know any of his friend group except for one guy who I also quite dislike as he has previously asked me for nudes last time I was dating my boyfriend along with a bunch of other unlikable activities. My boyfriend constantly makes snarky comments about how I don’t like him for no reason when I think it’s completely rational... he says he understands why his friend would ask that from me since last time i was dating i didn’t behave loyal and “got passed around”. (i did cheat on him when i wasnt happy in our relationship due to how he disrespected me instead of leaving because i was a pick me). Now I told him today that I hate it when he goes out with his friends and instead of asking me why I have that opinion he said okay so i said “do you not even care to ask why” which ended up causing a massive argument. I went on and on about how every time I told him something that bothered me he would disregard it and invalidate my feelings whereas he said some random shit about how I make him guilty for hanging out with his friends and am disregarding HIS feelings even though he had just brought that up during the argument after I mentioned for the first time that I feel uneasy when he goes out with his friends and didn’t given get the opportunity to tell him why cause he didn’t ask. Every time I bring up a concern such as this to him he either flips it on me or disregards it hence why I feel like I can’t even be open with him. I asked him many times to work on our communication skills and try validate my feelings but he never actually does. what should i do
