Get Involved

This girl I've known for a few years liked my boyfriend. She would always try to make me jealous by hugging him or anything she could think of. One day she posted a bulletin on MySpace all about him and I told her she shouldn't talk about him like that. She ended up harassing me online, calling me names. But when I went to school she would never say anything to my face, she denied ever saying anything to me when I confronted her in front of her friends. Then when I went back home she kept doing it over the computer. Her insults getting worse. Then I went to school and confronted her again and got in a fight. She hit me and I beat her up and now I don't know if that was the right thing to do. What else could I do?
