Tons of lying, tons of "misremembering" and self-pity and general "I'm an awful person you should never talk to me again" to make him feel bad for her and then getting pissed when he expected her to actually make an effort to rebuild their trust. I don't know if you should care, but I generally refuse to respect or support people who are abusive, and this isn't just a cut and dry witch hunt for no reason, imo. Honestly I think people are sort of brushing this off because it's a woman abusing a man situation. I've seen male users on tumblr be ostracized for less, with less evidence, when it was revealed they were abusing their partners. TRP calling him a "beta" and other dudes mocking him is gross.

Also, they established early on in their relationship that if a person is cheating, they are having sex with their partner without their consent. Thus, she was violating this man's consent for months, and she also claimed to have been tested for stds while cheating on him but refused to show him the results. And she guilted him into cutting off a friendship with another girl. Basically if you look up any "signs of an abusive relationship" checklist, the things she did hit a lot of them. She's an abuser, and that should not be tolerated or supported. I don't think it's any different from refusing to support or give money to people like Mel Gibson or whatever, or Alex Day being driven out of the YouTube community. She shouldn't be doxxed or sent death threats, obviously.
