Girl I'm dating (potential to upgrade from plate) went to a bbq and got with her best girl friend while drunk. In my eyes this is unacceptable and should be addressed.

My immediate reaction is to nip it in the bud and when when i next see her say something along the lines of 'if you ever do that again, boy or girl, you can go ahead and delete me from your contacts' and leave it at that. Stern, to the point and certainly not inviting her back to mine.

What would my trp brothers do in this case?
