Burner because obviously. I've (M22) been with my girlfriend (F23) for 1.5 years now. She is incredibly erratic and short-tempered, and has hit me, drew blood, and been both verbally and physically abusive to me ever since I first tried to break up with her 3 months ago. That time, it was because we always got into arguments and I saw no way out. Additionally, she lives a 6 hour drive North of me so I didn't see much of a point in continuing an obviously incompatible relationship. I will not avoid accountability here, the arguments were about 50/50 in whose fault they were, it was not all her.
When I told her I wanted to break up, she completely flipped out and started threatening me. She threatened specifically to spread to everyone I know, my family, the police, etc. that I had done horrible things. I confronted her about making stuff up and how dangerous it was for me but she just didn't care. It was like I was a toy to her, something she could torture with no remorse or consequences. She is incredibly stubborn and self-convinced so her justifications, such as that "I'm a bad person" or that "I'm irritating", are nonsensical and impossible to disarm. She also has the ability to "shut off emotions at will" which just sounds like psychopathy? I probably should've seen this coming, but Idk if that would've changed anything. She has gotten furious at me for such mundane things as studying mechanical engineering because my possible future jobs would be contributing to world imperialism or something.
I'm broke, as is my family. She is wealthy, and so her threats about having the funds to sue me in perpetuity have weight. She wanted to destroy my life and had all the power in her hands to. Obviously I got back with her to avoid this. But nothing has changed. She will push my emotions to extremes (through verbal or physical abuse) to the point where despite the threats hanging over my head I still will try to break up with her, and she will actively berate me and threaten me until I again agree to be with her again. Additionally, her justification for physically hurting me is that I can just defend myself (I am bigger and stronger) but I don't believe this is fair. I have tried to document this, both by trying to photograph marks and by filming her to get her to stop, but it never leaves a noticable mark and she always stops as soon as I start filming so I was thinking maybe setting up a hidden security camera in my room? Anyways, I don't need sympathy, I need advice to escape this situation. Thank you.
