Instagram Models

I have had an ongoing heated argument with my bf about the women he follows on instagram. We are both interested in similar hobbies that I introduced him to. That being said some of the pages he follows relate to those hobbies/talents/sports/etc. but I can’t decide if I’m just being a psycho bitch when I see 80% of the pages he follows are half naked women, who are way way more attractive than me. It kills my very small amount of confidence. I’ve lost 10 lbs while I’ve been with him hoping he’ll give me similar attention as the ‘imaginary women’ as he refers to them. Are my feelings justified??? I can’t get over them I’ve tried so hard. HELP
