Is it ok for her to be mad after what he did to me?

today in class there is this boy who always talks disgustingly so I hit his arm but then he touched my boobs. then he was being even more gross and talked about seeing little boys in locker rooms so I told my other friend and he touched my boobs again. then I slapped his arm, slapped his face and pulled his hair. in addition I told the principal and he's suspended for the rest of the year and can't go to the dance with this girl and now she's giving me crap about it. I don't think its right of her to be mad at me because I should be able to tell someone if someone's harassing me. the principal and the school police officer even said I could take him to court but I'm not cause that's just taking it too far, that's how serious it was. do you think it's right for her to give me crap for reporting the incident?
