My boyfriend thinks I'm doing things to purposely hurt him or to start fights. The other night, he was in a bad mood from having to deal with some roommate issues. So I asked him if everything was ok and he said it was. Then he started playing a game. But he was still frustrated while playing the game and asked me to take over. So I agreed to take over for him so he could lay down but then when I got up to take his place, he didn't move so I said "Ok, I can take over for you now, you don't have to play anymore." I noticed that he was still frustrated and was clicking furiously so I told him that it was fine and I would take over so he could lay down. He took it as me trying to start a fight and purposefully trying to annoy him. He said it was obvious that I was trying to start something because I asked him if everything was ok and then tried to annoy him by trying to kick him off the game. I told him I just noticed that he seemed grumpy so I asked if he was ok and then I tried to help him by taking over like he asked me to. Then he got mad that I always do things on "accident" and that I never own up and admit that I like starting fights. This scenario has happened quite a few times. Things got really out of hand when he blew up because he thought I was picking my fingers. He had told me the night before that my finger picking habit reminded him of "everything that he hates" and so the next morning I caught myself about to pick my fingers and so rubbed my hands together instead to stop myself from picking. He got really mad because he thought that I did it on purpose to trick him into thinking that I was picking my fingers to make him mad. That time I told him that I wasn't picking my fingers and I knew I was about to so I changed it to just rubbing my hands together thinking that would be better. But he said that's my excuse for everything that I always do everything on accident.
I'm not really sure what to do at this point. It's frustrating because I HAVE NO INTENTIONS OF HURTING HIM! What do I do? Am I supposed to admit to purposely hurting him when that's not at all what I was thinking?
