Girls, Girlfriend going to prom with her ex?

Anonymous
I dated this girl since she was a sophomore and I was a senior. I am now barely 20 and she is 18 (a senior in high school). We decided to take a break mid year so she could have a senior year and go to dances and stuff. Well we still act like we are a couple. We kiss. Cuddle. And hangout multiple times a week. I still refer to her as my girlfriend. She says we can get back together when she graduates. Well tonight she got asked to prom by her ex who I can't stand and she is going. She said she doesn't care who it's with because it's gonna be her second dance all of highschool (first being with me ). I have to let her go because I don't want to hold her back but gosh this is killing me. Girls what is your opinion? We had a huge argument tonight... Please give me some advise.
