What to do?

I have an 11 year old and a 1 year old. They are not by the same man. My current boyfriend sometimes wakes up and kisses he is baby but doesn’t always say anything to my 11 year old. I don’t usually say anything because it turns into an argument. Today I said “why didn’t you say anything to my oldest?” “I have 2 kids, not one”

His response was “why are you so annoying, don’t force me”. My eldest has his father in his life but his lives further away and doesn’t see him often. They speak on the phone all the time. It bothers me because a “good morning” doesn’t hurt.

I’m tired of it. Am I being dramatic? That’s how he’s made me feel about the situation..
