*Edit: Sorry about the second "wants me"

So lately, we've been fighting more than usual. It's my fault because I suck at communicating, but also whenever I say something, it's acknowledged for a second and that's it. So I just don't say anything and he repeatedly asks me what's wrong. I don't want him to ask me, I want to process it and he doesn't let me. A few weeks ago, we got into a fight about me saying anything so he threatened to break up with me if I didn't talk to him. We talked about what was going on, he's fixed it. It was done.

We just got into a thing last night about intimacy stuff and I brought something up (not getting into specifics), and he had a rude response the night before when we originally talked about it. I told him that I wanted to talk about that sometime when he said that, and he was like "why?" as in why would we talk about like it wasn't a big deal, so I said nevermind and I apologized for bringing it up and being selfish (honestly, now that I think about it, I don't think I should be sorry because I help him with this issue more than he helps me or even tries). Plus I was packing for a conference at that point, and I was busy and that's why I couldn't talk about. We talked about it again, and he was like "you apologized, I accepted, I thought we were done," and when I told him something about how I don't want to feel upset about this or feel like it's my fault for starting a fight and I'm selfish for bringing it up. The only thing he focused on was him not liking that I say that I shouldn't have brought it up but he proves my point. So when I did say something about it and actually talked about it last night, I basically said, "well I didn't say it right away so just break up with me. You say that if I don't tell you right away, you'll break up with me. When I say something, you don't say anything really except for a little bit."

Tonight, it happened again. I told him that I don't know if I can be vulnerable with him where I could cry or puke (if I'm sick) in front of him, and he was like, "I understand, I'm going to sleep." Like? I just don't know what to do anymore. I really try to communicate, but it doesn't always work. I don't want to break up, I don't want him to break up with me, but I don't know what to do.
