Can someone give me some advice and tell me if i was wrong?

It sounds to me like she was just being jealous. From her perspective, her best friends was stealing her time away from her with her boyfriend, which angered her. Keep in mind I'm not on any side, but she had logic from her perspective. Now from yours, you had logic as well. In all my experience with dealing with people, i learned to just drop some things. She was drunk. That was the first and most important indicator that you should not have begun an argument in the first place. Alcohol poisoning makes people irrational and hard to deal with. You should have gave her time to sober up. Overall, your both at fault here and both wrong. Her for her actions and you for provoking it. uming i have read and understood everything correctly that is my opinion
