Am I wrong here?

Me and my boyfriend were just chillin out and he started blasting music, which was cool but then he like puts on these two songs and goes while he sits by himself looking super sad and shit and they were about like first loves and shit, so I thought he was probably thinking about his ex fiancé who he was with for 7 years before we got together. He was in his own world and when I say he looked sad af I mean super down so after that he tries like dancing with me and i was just full of anxiety and of course I didn’t want to say anything but I was just like are you okay? Like are you missing something? Then he just like pushes me off of him and he’s like oh fuck you I know exactly what you’re thinking I’m thinking. Now he’s being so fucking rude to me saying I think about my ex boyfriend and shit? I don’t get it I just asked him cause he seemed sad. We have been together a year now. I wouldn’t think he was thinking or being sad about his ex if he wouldn’t have given me that vibe.

But now he’s calling me crazy and flipping out on me. Was I wrong for asking? Am I in the wrong here? I have apologized and tried talking to him but he’s being horribly rude.. saying he doesn’t even want me near him. So now my anxiety is off the wall bad...
