When i was younger i dated someone that was what i would call abusive. I can give an example here. I was at our state fair. I was out with her. I saw someon wearing a Neon Green top, like impossible to miss. It was a girl, i glanced at it because its green, like fluorescent green. About 10 minutes later she starts shouting at me, saying i was staring at the girl's boobs. i tried to explain that it was a shirt. She balled her fists up and breaks my nose.
Before that incident, i was out with her for our anniversary. I was in a grocery store with her, getting stuff for the meal that i was going to make tonight, and as i was checking out, i decided to have a conversation with the girl that was ringing me up, this was in effort to pass the time. As i am walking out to my Blazer, she trips me and starts kicking me screeching at me that i am cheating on her with that girl, and the act of me talking to her is the same as cheating.
Just two of the 50 or so incidents that happened during the 2 years that i was with her. Eventually while she was at work (btw her opinion on money was if i work i am to pay the bills and spend the rest on her, if she works it only gets spent on her) i gather up all of her things, put it outside of my apartment, get with my land lord, change the locks and call her brother up and tell him that her things will likely get stolen if he doesn't come by and pick it up. That sadly was not the end of her interaction in my life. Later on i start dating my wife, and she does everything in her power including but not limited to attempting to hack my face book to calling the police on me to attempting to hurt my wife to mess things up.
Sorry for the long opinion.
