What to wear?

Kimberly • First time pregnancy and mom....all advise is welcomed 🤗
My boyfriend has always felt a way when I wear certain things because I have a "nice butt". Now I have a baby bump and a booty bump certain dresses I put on he becomes outraged and insecure and "forbids" me from wearing them. I am proud and happy to show my baby bump off and is it my fault I have extra junk in the trunk? I have the most respect for him but what should I do?
