My boyfriend is mad at me because he had to watch our daughter while I take a bath

Omg. So I have been working from home all day with our 9 month old daughter attached to me the entire time, which is fine- but my boyfriend also works from home and didn't help with her all day.

So I told him I wanted to take a bath and his first question is "with the baby?" And I said noooo, alone. I want to relax. Well then he gets butt hurt because i CLOSED THE DOOR! He starts going on about "cool have fun doing whatever the fuck you're doing". Like what? I cant take a 30 minute bath to have some freaking privacy and relaxation.
