emotional abuse? autistic relationships?

Em
My boyfriend has autism and OCD. He's the cutest guy in the world and so sweet caring and great to me. You couldn't tell from just looking at him that he had autism or OCD. My problem with our relationship is he obsesses and gets so confused and angry and frustrated about what I say or just like random things like that. Sometimes he hears me say something or I'll answer a question he has and he'll have me repeat it for hours or even days and if I don't he gets so frustrated. Like for an example I said "everyone loves you so much baby" and he had me say it with the same emotion in my voice probably 200 times. If I'm ever in a bad mood he gets frustrated. He always thinks he did something wrong. I'm always apologizing for things I didn't do wrong just so he's happy. Is all of this emotional abuse? Or is it just him being autistic. We've been together for almost a year. I'm too invested now. I don't know how i could ever break up with him, he's amazing. I just idk help. Please give me some opinion.
