AITA for no longer wanting to be friends with someone?

I've been friends with Maxine since childhood. We even dated sometime as kids. Maxine has really changed through the years, going from an energetic lesbian who quotes movies and memes to a "prim and proper" devout Christian who wants a Christian husband and Christian kids.

Here's where I lost it. Maxine, first off, continued to be friends with a woman who stalked and harassed me (though she stood up for me when it happened), a woman that bullied me, and someone who tried to get me to take my clothes off or they'd beat me up (They didn't).

There was one time where I asked Maxine why she was upset because someone told me she was, and Maxine said "None of your business, fucking retard."

Maxine also kind to used to treat me like I had the intelligence of a five-year-old or a pet because of my autism.

Maxine proceeded to talk behind my back and say that the world didn't revolve around me and that I was just a stupid, annoying brat who people only pretended to like because I sucked so much.

I got mad, started crying, and she didn't even apologize. We don't talk anymore.

So, AITA? Am I the problem?
