Does this make sense?

Okay so my best friend was in a fight with this girl that REALLY doesn’t like her, and it kinda happened before too but no one got hurt the first time. She asked me to go get a teacher, I waited for a couple to see if she was going to be okay until I got back, and then I left. By the time I came back everything was over andby best frien had been kicked in the face twice. For some reason the other people there didn’t bother to pull them apart when I was gone, and the teacher decided to go through the whole crowd of people (almost the whole school was watching) instead of going the other way with only a puddle. So she has decided to shut everyone that she feels betrayed her including me out of her life. I understand that she is hurt but she sent me an im that sais she didnt want me to contact her at all ever again, and I don’t think I really betrayed her, maybe I should have pulled the girl off her before I left, but the last time she said that the girl wasn’t that strong so I figured she would be okay.

Do you think she is doing the right thing cutting everyone out of her life? Oh yeah and she’s moving in less than a month so she figures that she’ll just start over and everything will be okay then.
