Instagram jealous

I’m 37(F) and my boyfriend of 18 months is 43(m). Even though we are opposites in most ways, we are really compatible and he’s my best friend in the world. I’ve never loved anyone like I love him. But he has had Instagram for over 10 years and has accumulated several women who post provocative photos and he responded to many of them in the past with comments expressing his appreciation for their photos. He unfollowed all of the thirst trap girls I asked him to unfollow. I recently saw that at 5 months of dating, he liked a few provocative photos (many from someone he actually knows who isn’t in our state). I haven’t seen any likes within the last year and the ones from our early relationship he said were just him saying hi, not him admiring the bikini photos. However he liked a considerable amount of her photos in the past before we dated and even commented on some but he says he isn’t attracted to her, they are just close friends. Being that he hasn’t liked any photos in a year, how do I get over it? I really don’t want to break up over something so stupid but I’m hurt and feel even worse when he says he isn’t attracted to her. Literally believe this guy is the love of my life. Am I being too jealous and stubborn? He doesn’t want to unfollow her because she is his friend and for the principle of it. He feels because this is a continual fight, we might need to end things because I don’t trust him. I actually do trust him but feel disrespected in this situation and think I will continue to feel even more disrespected if he continues to follow her. I never want to be the kind of person who controls him but I also want to advocate for myself.

TLDR: My boyfriend follows old female friends with whom he has liked and commented on provocative photos. Am I being over the top to expect him to unfollow
