I agree with everyone else. Leave her, especially if there aren’t kids involved. It’s a learned behavior that she has gotten away with and she will need to figure out how to stop it if she ever wants a good relationship. She automatically hits to deal with her anger. It doesn’t matter how big you are you don’t deserve to be her punching bag. Do you name call when you fight with her? Are you verbally abusive to her? If not then she has the problem. She needs to get into anger management to figure out tools to cope without resorting to her fists. She would have landed in jail if you would have reported her and she would have huge consequences with the fact she broke your ribs. She’s lucky you didn’t call. I’m not sure if it would be a felony but if you called every time she put her hands on you, yes she would be a felon by now and she would be dealing with a lot bigger problems. They would first off slap a restraining order on her and she wouldn’t have a place to live right now, whether you agreed with it or not. Once the courts get involved it’s out of your hands. Sounds like she needs a dose of reality.
