Should I call the cops on my girlfriend?

About 10 months ago, me and my girlfriend watched the movie Watchmen together. She was really inspired by the Silk Specter character and began working out. She began to look really good, and damn she was hot. Then she made herself this tight latex out fit over at her friends house, and began modeling in it for me. At first, I thought it was a sex thing. Then one night she told me she was going to fight crime, at first I laughed and told her no. Then this angry look over took her as she picked me up and threw me across the room. I began to fight back but she was so much stronger than me. We fought the whole night, she didn't have a scratch on her, I had a black eye, bloody nose, she stretched my under ware (essentially she gave me a wedgie), and I'm afraid she will do it to someone else. Also, I don't like it when the woman is the man of the house, what should I do?
