ya girl here needs some help

and its actually quite serious this time

so i have this person in my friend group. the two of us were really good friends up until the middle of 8th grade for a reason i just found out (we'll get to that later) and she would ignore me for no reason and she avoids me whenever she sits in our little friendship circle (which is rarely unless she wants to talk to us about bnha) and shed exclude me.

turns out a friend in my french class told me that this girl spread a rumour saying i stalked her (truth: i saw her in front of the bus stop from the other side of a busy road and waved at her) and there is another reason why this girl hates me and you might not believe me, but it's anime tastes. this girl starts a feud with me and avoids me for 3 years because of our tastes in anime, which is just...really stupid and imo immature.

background on our tastes: this girl likes bl/yaoi anime which im fine with. back in the day she'd show me some pretty explicit shit (like otayuri or viktuuri doing...the deed...) and im fine with that. she also like shounen anime (fairy tail, sao, black clover, you get it) and she assumes that i only like these idol anime and she hates me for that...because...if i like love live it completely defines me as how i am as person...? (again a lie, because i have watched bnha, yoi, fairy tail, sao and more and fun fact: my in-game comment in bandori is literally "stan otabek altin") (which is something yall should do he is underrated)

anyways, is there any way how i could confront her about this + be friends with her again? also this was a long post, and i do apologise

UPDATE: I read the comments, and I tried them all today~ I tried talking to her in private, confronting her about it, and she just put her headphones in like as if nothing happened. i tried to get a friend to confront her, and the only thing she said was "maybe if maru here didn't get into the toxic fandom, maybe we would still be talking" which basically proves that the only reason she hated me was because of my tastes. i think maybe ill adhere to the recommendations and maybe try my best not to associate with her in the future =^.^= (which is hard because she comes over to talk about bnha and i really want to go into the group sometimes) but anyways, thanks for the support and the advice ʕ◕ᴥ◕ʔ

edit: yall i got one of my friends to watch love live and now she wont stop talking about it, and iT ANNOYS THAT GIRL SO MUCH THIS IS WHY IM FRIENDS WITH THEM ASDFGHJKL
