Well first off is it bluepilled to even have female best friends?

My so called best friend is a girl who clearly has some sort of drug induced bipolar disorder. We've been very close friends for a year and a half (I have zero sexual interest in her) however she suddenly switched on me (for no explainable reason) and has been abusing me verbally everytime she sees me (in front of mutual friends) and harassing me through text trying to fuck with my mental health. However I'm sure by this time next week she will be messaging me asking to be friends again. All my friends are sympathetic for me but still continue to hang out with her instead of me because she is a "life of the party" type girl.

If it was a male friend saying these things to my face I would be well within by rights to punch them in the fucking face and tell them to stop talking shit and I would have the respect from all my friends for doing so. Obviously because it's a girl I will never touch her and if I would i'd be socially ostracized completely.

This is sort of a vent post but I also genuinely would like some RP advice on how to deal with this sort of situation.
