I got into an argument with my bf awhile back about following and liking these slutty instagram post/pages. You know the instagram slutty "model" type pages. Well I had told him I don't like it and he unfollwed the pages and stopped liking pictures like that, but I recently checked his history on his phone (I know, snooping is wrong, don't judge me) and I saw he was looking at this one insta profile. A pornstar or some influencer who post slutty pics. I got so mad and an argument broke out again. I admit I feel insecure about it. Over the years I gained some weight and feel even worse about it when my bf is looking at other women online. The past year I lost over 40 pounds because of it and I gained some confidence back but I'm still not where I want to be physically. I had a baby recently and that halted my weight loss and even more now my post pregnancy body is making me feel very down about my looks. I told him I don't feel like I'm good enough and even if I lose more weight I may not ever be good enough for him. He told me it has nothing to do with my looks and he finds me sexy but I still don't get why he has to look at things like that. It just makes me mad that he knows I don't like it yet he continues to do it. I know some women don't care if their guys like pictures or look at other women. We're human. We find people attractive, I get it, but if my s.o felt insecure I wouldn't add to the insecurity. So should I be mad? Do other women care if their guys look? I feel angry but at the same time I feel like it's stupid to be upset.

Update: I agree what he's doing is immature, and I told him that as well. I walked away from him while we were arguing and he said "very mature". I spun around and replied "yeah, as mature as you and your 12 year old hormones getting your peepee happy looking at tits online" I told him he's 30 years old not a fucking teenager and to grow up already..that I don't have the energy and I need a man not a child. He said he was looking because we haven't had sex in a few months (I was pregnant) and admits he got a little horny and was looking. I don't care the reason. Sex. No sex. Don't care.
