Am I in the wrong???

Mi

So I’m in a group of friends and we were all going out together. We were all getting along fine until on of them (it’s always the same person) ripped my hair out all because my other friend who was sat next to me wanted to change the song on her phone and gave the phone to me because I knew the password. She got all defensive over her phone and ripped my hair. All my friends shouted at her. This isn’t the first time this has happened she usually results in violence and has slapped me before for silly reasons.

Every time she does something like this I end up forgiving her!
