Dealing with my boyfriends possesiveness.

I love my boyfriend so much! But sometimes he can be really possessive, especially over what I wear. He says he’s not being controlling, and I know full well he isn’t, but sometimes it’s really difficult to check with him each day if what I’m wearing is okay. Is it just me? Should I be more allowing? I understand he isn’t meaning to be controlling, but sometimes it’s just so difficult. I love him so much though!
