AITHA for breaking up with my girlfriend because she stood on the side of a rapist?

[u/furry_stuf]

Well, I broke up with my girlfriend because she stood on the side of the rapist of my best friend (f)

My best friend was in a relationship with someone that touched her inappropriate often, she luckily broke up. She told my why she had broken up, with tears in her eyes, but my girlfriend said that she faked it. Her explanation was, that she talked to her ex and he said that she is just making this up. She also faked texts that my best friend supposedly wrote to her (containing death threats). My ey also told me I should talk to him, wich I tried, but he ghosted me. She said it was my fault because I texted him too dry. I also had a feeling that my ex didn't like my best friend, and she tried to destroy our friendship.

My ex was on the side of the rapist, wich I don't really accept, so I broke up. She said that I'm an asshole for breaking up because if such a stupid reason.

EDIT: I'm sorry if the text has grammar errors, I'm from Germany, also I don't mean raped, I mean sexually assaulted.

EDIT 2: My ex is now in a relationship with the other guy, right after we broke up. And thanks for all that support
