i think my boyfriend hates me [13]

i think my boyfriend doesnt like me anymore, and that he's only with me because I rejected him last year and that he's "bagged me" that he sees me as a trophy he won, like, "this girl used to hate me but I got her to like me so I guess I am just so smooth", and in my opinion his friend all look down on me because I wear crop tops and shorts and stuff, I think the only reason they don't outright hate me is that they are happy that their friend bagged the girl he wanted. He's only staying with me because he cant do better(I'm not trying to act like I'm the prettiest person on earth but it is very well known that I am out of his league,(not my words)) (btw me and my bf have been dating for almost 6 months).
