Drama

First and foremost I know my part was in what I did. Just wanted some opinions from other females.

So it was my friends baby daddy b day party. Everything was messed up from the gate. We were to BBQ then go to the casino nice. His mom got upset he didn't want a BBQ right after we got the food.then he invites the whole neighborhood. And food drops and he ha to get a BBQ from his cuz making more people come over. everyone is of age I kept an eye on the kids till my friend and I invited a girl who was a friend to both of us. (We both have a bad past with her and she was going to get punched sometime at the party). At some point I get little tooo tipsy and beat her in the face and yes if we had beef it should've not gone on at a party. But everything was done no cops called and the girl was allowed to stay and not me and I hit my so in the neck and he hit my face struggling to get me in the car. Do I have a right to be mad that my friend chose her old friend over me?
