The BOM Ambassadors say

Well if she won't talk to you, you could try other ways of getting in touch with her to try and apologize. You could email her, text her, facebook, myspace or even try talking to a friend of hers to explain how you want to apologize. if she does not respond to any of these, then you should probably just give her space and time. But what you should also consider doing is apologizing to the guy you tried to fight. If you do that, it will show her you are being mature and you are taking responsibility for your actions. Just continue modeling mature respectful behavior to prove that you are sorry and are changing.
