Geez NataleeRose, this sounds awful.

My own main question is, how do other people react to this?

This is abnormal not to mention mean. Does he exhibit other narccisistic behaviours? You have mentioned having normal couple fights. Just what exactly do you explain away as this? I am greatly worried by this statement.

Someone else posed the question that there might be something in his past directly responsible for this - like a parent taking away his pet in childhood. I think it worth delving into.

Finally, I agree with all the others that this is a dealbreaker. It is time for a talk about expectations and boundaries. You have mentioned Autism. I'm going to come right out and speak my mind about this.... could this label be an excuse for you to accept other unacceptable behaviour?
