i feel like my bestfriend hates me

(24/03/25) **EDIT**: i dropped her and now i have new friends, life is so much better now <3

she never calls me or texts me anymore, she's ''popular'' now so random ass girls hangout with us during lunch, we always have to walk around when i want to sit down and she's so crazy about her boyfriend so we always have to follow him, it just pisses me off.

she got mad at me a few months ago for getting close with one of the guys in our friendgroup and now she's all bestied up with him and i literally hate it, i can't say anything about it because she doesn't care and if i stop talking to her she probably won't even notice. but when we're alone she actually treats me like a person, i hate her but she's my bestfriend and i just want her to go back to normal, she's weird and confrontational and also a bitch, i just have no clue what to do anymore.
