Why do girls don’t like me? 🤔

In middle school I dated the “popular guy” I was cool with all of his guy friends as if I was one of the homies lmao, but his girl friends never liked me 🤔 one of them was like my best friend but she was a hypocrite why? Because she was talking about me and she didn’t like me, well all of his friends never liked me, even if I didn’t know them , I’m not a mean person I used to get called adorable and very nice girl, idk is it something about my personality?I was in 7th grade, he was in 8th grade I got along with the 6th 7th and 8th graders, all of them. but his girl friends were just so rude and mean mugging, never really talked to them, but I somehow would find out they talked bad about me, idk...

I don’t consider myself mean.

I had another bf who was a little more older than me, his girl friends never liked me, I found out by my cousin that they were talking bad about me, one of the groupie was my “friend” also but I always get a vibe from her that she doesn’t like me, but I always was cool with his guy friends ?? So idk help me understand, I think I’m nice
