Boyfriends making me feel insecure:(

Basically right now I’m crying:( my boyfriend was obsessing over famous women,saying how perfect this specific women was the perfect women and had the perfect body and was just constantly talking about her saying about how he wants her to be his hall pass. I’m so upset like this seems so petty but it’s upset me so much like I have really bad insecurity problems and this hasn’t helped at all, he knows I have this problem and him saying how perfect she it makes me feel like crap. I dont know how to talk to him about this because its not that I dont want him to talk to me about this sort of thing because I know deep down we’re stronger than this but I’m really upset and I want to get my point across without seeming petty. Can someone help I’d really really appreciate it ❤️
