Advice?

My boyfriend’s a youtuber, okay? He streams, posts videos, etc. Usually they’re with his friends.

I was watching one of his videos the other day, and I heard something that made me uncomfortable. See, I’m autistic and he knows that. In the video, his friend used the word autistic to mean weird or dumb. He laughed along and started making jokes.

I’m upset. I don’t know what to do. I mean, I know he shouldn’t have to censor himself on his channel but I don’t understand how he can date someone autistic, call her smart, tell her he loves her, but then go on and make jokes about her disability.

I don’t know what to do. I don’t even know if I should be upset. Please help me.
