Fiancé thinks I look ugly while pregnant...

Fiancé told me his attraction has faded towards me since my belly has gotten bigger while pregnant... He told me if I don’t lose the baby weight once baby comes he doesn’t know if he will ever be attracted to me again. He said pregnant is not a good look on me. If I eat one little thing (for example, he ordered a whole large pizza to himself and I took ONE slice) he says “are you sure you should be eating that” and “enjoy it now while you can before you go on a diet after the baby is born.” He eats nonstop but if I eat one thing he judges me and makes comments. Every time. According to my doctor I have gained a healthy amount of weight so far. He also told me that he would appreciate if I didn’t breast feed in front of him, to do it when he’s not home/in another room because he finds it nasty, and to always use a blanket no matter where I am just in case he accidentally walks in.

Would you be upset or is he right to say these things?
