Struggling w my boyfriend

My boyfriend used to eat me out all of the time but he hasn’t recently. It was one of the two things that would make me orgasm. The other was me masturbating. We used to do a thing where I would give a bj and he would eat me out, but after he cums he wouldn’t help me w anything. Even if I tried to please myself I always felt weird because he would look at me strangely. I would always be sexually frustrated because I’d be super horny and in the end not get anything. Idk what to do.
