<human>: FML. I'm a male 21 year old college student. My girlfriend is a dancer, and has a event later this week. She has many friends from dance, whom she dances with, and I will get to meet them for the first time at this event. I was shown a picture of them, and to my horror, one of them was an old tinder hookup that lasted a couple days and ended rather unpleasantly. I know that I will be forced this weekend to meet them together, and she will recognize me, and the shit will hit the fan. Do I tell my girlfriend before the event, after the event? She is friends with this girl, and has no idea. The girl wants to meet me too, to meet her friend's new boyfriend. Agh... I dont care about drama and can be an adult, but I dont want to cause any division between them, since they are friends and teammates. What do I do??

Provide a brief overview of the text.
