Hi! Need some advice.
My best friend has been very weird to me ever since i got a boyfriend.
For context we've been friends for 2 years and go to the same school and sit next to each other in all classes. But about 8-10 months ago i broke up with an ex and 7 months ago i found the love of my life.
At first she was very happy for me, but soon she started to change, talks bad about him (she doesn't know him or anything about him except for what i've told her) even when i tell her to stop, disrespect me and say mean/ugly things to me (for example we had a project at school and i edited some outtakes and showed her. I said "thank god i'm not as embarrassing anymore lol" and she said "you're even more embarrassing now" and turned away coldly.), she and our 3rd friend (we're a trio) also keep distancing or excluding me from conversations. whenever i talk they talk over me but when they talk over each other they apologise. I've also heard from other people that they talk bad about me whenever i'm sick. They do a lot of "bad/mean" things but i cant list them all.
It's gotten so far that i've cried to my boyfriend as to why nobody likes me and why i cant have a real friend. (I have nice people i talk to at school but i wouldn't consider them friends, more colleagues)
She's been a changed person ever since i've been with my boyfriend.
Part of me wants to believe its just a phase but i know its not. She also has a boyfriend of 2 years so it cant be jealousy. Her boyfriend also kind of talk bad about my boyfriend, they do it together just because his style is different and as they said he's "too social and extrovert" when they met him (which was once and then never again.)
I am a person who cannot stand up for herself and no matter what she does i would never be able to defend myself. I can defend my boyfriend from them but never myself.
I need some advice on what to do here as she's basically my "only friend" in school. I've already stopped telling her about my private life+boyfriend+problems.
Would really appreciate some help. Thank you!
