First relationship with my boyfriend is making me unhappy. Unsure what to do.

I (19 almost 20F) and my boyfriend (20M) have been dating for a year and a half. He has BPD, OCD, ASPD, and other mental health issues from trauma. I also struggle with my own problems but I’m undiagnosed. When we first met, I was selfharming and was deep into anorexia/bulimia, drinking, and smoking. I stopped all of that because he doesn’t allow me to, which has been very hard since i stopped all of it together and it was my coping mechanisms but he has also helped me recognize red flags and leave toxic friendships and even distance from my parents. (one of the reasons he rented a place was so i could leave my family)

The problem is he gets upset very easily. He says if something annoying happens, of course he’ll be upset, and this happens 90% of the day. He doesn’t remember what upset him later, but it drains me because I always blame myself. he doesn’t get annoyed at the person who did something he gets annoying about the fact that the annoying thing happened.He also has insomnia and refuses to get help in any way because he thinks nothing will work.

We also basically live together. When he was unemployed, I worked while also cooking and cleaning at his place. He only did dishes sometimes and laundry. Now he has a job and cooks sometimes, but I still clean up.

Another issue is our sex drive. I don’t enjoy sex because of trauma, but he has a very high sex drive and makes almost everything sexual. He touches me, slaps my back, even in front of friends. We talked about it and he stopped for a while, but then started again. He acts like it’s just joking, but I don’t like it. I also kinda don’t enjoy kissing him anymore (also he can’t make me finish even though I can by myself… but i also understand i have weird sensory issues)

He struggles to be without me. I once planned to visit my village for two days but canceled because he couldn’t come. I also want to go to a concert in milan but he said we aren’t financially stable. I understand since im helping with the rent but I’d like to go without him but I’m afraid to bring it up.

Sometimes I don’t even want to see him. I don’t know if I love him. I don’t know if he is the problem or if I am. I have a hard time opening up, but I try, and it’s a really big achievement for me that i even talk about stuff that bothers me. he still gets annoyed when I don’t tell him things immediately.

I don’t know what to do. Should I break up or give him another chance? Is it too late for this to change? We share the same friend group, so it would be very awkward. This is my first relationship and I’m really lost.

TL;DR: I (19F) have been with my BF (20M) for 1.5 years. He has BPD/OCD/ASPD and is upset 90% of the day, refuses therapy, and makes everything sexual despite my trauma/discomfort. I basically live with him, cook/clean a lot, and gave up my old coping mechanisms for him. He gets annoyed easily, struggles to be without me, and I ameskipped a trip/concert because of him. I’m drained, not sure I love him anymore, and don’t enjoy sex or even kissing. Should I break up or give it another chance? (we share same friend group i feel like it would be awkward)

Edit: i don’t know how to break up with him without feeling guilty and worried over how he will deal with it, plus im scared i’ll regret it. i sometimes have very good time with him and we talk about alot of stuff we enjoy
