It's not possible to file a charge in a bar scene unless a guy hit a woman or you are severely wounded. Police will look at both of you as two drunk dudes. I punched this guy first who was harassing me. Of course bouncers came and I voluntarily walked out of there. You can take advantage of that. In your situation, you were just unlucky. By the way, Was she kind of trashy girl?
I stay away from trashy people in general
