AITA here

So recently I told my mom I was raped and she basically decided to call my ex boyfriend to confirm if I was or not. Of course he fucking lied and I got upset she called my rapist infront of me and cried in a hibatchi parking lot for three hours because it’s like why are u even doing that it’s unecessary. Of course he lied and after I’m crying and telling her to leave it alone bc calling him isn’t gonna do anything , she still continues to do it and then he gets nervous when she asked and he sounds in shock and genuinely sounds guilty and says “can I call you back later.”so he can get whatever story out of his ass and she says to me “ugh your too much drama.” , and in summary I told her that a few days ago let’s speed up to recent moments we’re out of town, and I asked her hey can I drive us back to the airport so I can learn how to drive on the highways for spring semester? And she’s says let’s keep in mind (I was raped that’s the only thing I’ve told her about my sexual history) “oh since you’ve been sexually active I don’t think your getting my car.”( that she told me I was gonna get if I had good grades I have good grades) and I responded “I was raped.” And she’s says “that’s not what he said .” And I responded “oh so ur taking ur side.” And she says “why was he in your room in the first place it’s like your setting up the scene to be raped.” And I just walked away because I wanted to punch her so hard in her fucking face ?(let’s keep in mind the past few months she had an experience with a man that used her resources and had a second family and I helped her through that and was there for her never in my life I thought she would take a man’s side over mine) I just want to know your thoughts and opinions and if I’m the asshole for cutting her completely??? And she keeps trying to talk to me unnecessarily ever since I plan on moving in with somebody else because there’s just no way in hell.
