Thought SO and I were jokingly teasing each other (as in exaggerated accusing of cheating in a video game etc.).

turns out it wasn't funny to him and he now says I'm self centred, rude, boring to talk to and after I apologised and tried explaining myself that I didn't see him not having fun, he said it doesn't matter and that he doesnt care what I'm doing, he doesn't even want my apology because I'm rude and make him feel like shit. 

He said that to me 2h after the incident and he only said it because I pressured him to tell me what's wrong (he usually bottles up emotions and then explodes at me while I talk things out straight away) 

now I'm thinking: 
Is he saying that so I leave him
Is he saying that to prove that I won't leave him
Did he open his eyes and see that I'm not a sweet always happy girl and my humour is sometimes based on teasing one another
Or something else lmao

either way I'm feeling awful right now, I didn't respond to anything he said. and I don't want to communicate at all. 

I hate it. We're together for a couple of years and he just recently started getting really agitated at my jokes (practically calling me a rude bitch without using the word) or me saying I don't like his jokes where he calls me controlling. 

I do think he has undiagnosed autism based on how he acts in general and how he's misinterpreting what I'm saying or doing. He also always assumes the worst of me which is just the cherry in top in all of this.
