Boyfriend liking half naked photos of women.

I never thought I’d be the person behind a post like this as I have never been the jealous type but here I am, I’m 9 months into a relationship that has been going good but here’s the thing, I started seeing “name” liked this post and it was of all these women who are naked or pretty much naked, these beautiful bodied, perfect faced women and I couldn’t help but feel upset. Now, there’s a bit more to this and why it bugs me.... #1. he doesn’t like my photos and I know it sounds petty but I’m your girlfriend, you don’t acknowledge when I post a picture but got all this time to be browsing through and liking all these women’s pictures? #2. He has some insecurities and has talked about them with me, he said he doesn’t like when certain guys talk to me at work (we work together) and it really bugs him because he’s heard them comment on how beautiful I am, apparently. He never expected me to avoid these people but out of respect for him, I obviously don’t run up to them in a joyful time looking for conversations. #3. We’ve talked about how I bring some negative feelings about certain stuff from my previous relationship and although I’ve never been jealous, my daughters father was big into that stuff on social media, web sites and he time after time went behind my back and did shady shit in that department and I am fully aware that my new relationship has nothing to do with my past but call it a trauma, it just sets me off edge and makes me feel uneasy.

I don’t know, it just really bugs me because if the tables were turned I know he would be tripping. I feel like he set all these boundaries that we agreed on in our relationship and they completely don’t apply to him because I did mention it and he got defensive.
