Extroverts that cross boundaries

This is my first time posting here, and for context, I'm in senior highschool and an ambivert (most of the time an introvert). This goes back to the first day of school pa, but my whole class were pretty familiar with each other since one girl made a GC before the sy started, she was loud, cheerful, and she talked like she knew everyone for a while na, then nagpahotspot siya saken and I see no reason why need ko magdamot ng data.

It was fine, I was writing a draft for my novel since wala pa naman ginagawa, out of nowhere, she took my phone and told me to not use MY data muna so she could post stories on her FB and she closed all apps, I was taken aback since it was the first time na may gumawa saken non, but I let it go since baka nga napapabagal ng iBang apps na naka open sa background ko, so just opened my Wattpad again so I can continue writing my drafts, but she saw me do it and she got mad and closed it again, that caused my Wattpad to error and my draft didn't save. I confronted her and she got upset and sassy, saying na magdamot ako.

That same day, I was eating Kwek Kwek and she asked if masarap daw ba, I said yes, and she just replied with "Ganun pala pag private noh? di nakakabasa ng social cues mga tao, samin kasi sa public dati aalukin ka if gusto mo eh" Infront of our other classmates, so I explained na medyo always conscious ako and out of nowhere, she said okay lang and kinamay niya yung food ko.

Fast forward to more recent times, she's sat behind me na, and nag unat lang ako for a moment since matagal nako nakaupo, we have quite a distance naman so I thought okay lang. Unprovoked, she grabbed my head and pulled it down harshly (I was unprepared and heard my neck crack), she was so proud of herself that she was laughing, clapping, and screaming. Shocked, I screamed at her, asking her if she was trying to unalive me, and she just responded na I can't take a joke.

She's always like that, and when she found out na we had a car (not even a fancy one), she insisted na isabay ko siya and ihatid siya at her house, when I said I wasn't comfortable with that, she said ganun daw pala sa private (Forgot to mention na public school ako galing my whole life, ngayon lang din ako nagprivate).

Every chance she gets, she'd call me out for having strict parents, how umuwi siya ng 1 am and okay lang sa parents niya, everytime she gets, she publicly points out na I barely have anything fancy even if we're quite financially blessed, she brags how she spends 30k on her shopping sprees, she has an iphone, and she bought a husky dog, all while complaining na gawa lang sa plywood bahay nila and they live on the side of the road, how baon na sila sa utang.

She called me "Matapobre" when she asked me where ko gusto magcollege and I responded na me and my parents are planning ma mag La Salle ako, sorry daw kasi di nila afford yun.

That's all, I just needed to vent this out since I'm really uncomfy with her since she's very popular at school due to her friendly and cheerful nature, I really feel uncomfortable na sakin lang siya ganyan even if we didn't know each other before, and nung una, she really tried to get close to me but I distanced myself after she crossed my boundaries and I refused na ilibre siya after she found out weekly allowance was triple of hers.

Her other friends always dismissed this as only child and rainbow baby daw kasi siya so her parents love her that much to a point that they enable most of her behavior. While I'm an only child myself, my parents are very strict so maybe ganto talaga dapat yung friendships and I'm too sheltered?
