AIO for telling my boyfriend to work on his jealousy after he got upset that I dressed nicely for church?

I (18F) was on my way to church with my grandma and sent my boyfriend (19M) a picture of my outfit. He started acting jealous, questioning why I looked "so good" just to go to church. I reminded him it's a dress he complimented last week, and I wasn't even wearing makeup. I offered to have him join me, but told him I didn't like how he was behaving lately. He said he doesn't want anyone looking at me and that I'm "his". I told him he needs to work on his jealousy. AIO?
