Honestly I have to admit that I don't want to go to my girlfriends prom with her.
Did she do something to make you not want to go to prom with her?
She's very clingy during our time together and it's annoying sometimes.
I can understand you thinking her being clingy is annoying but you should go to your girlfriends prom with her. It's a big day for young women and really important that you be there for her. If you really do care about her it would be wrong not to go.
I shouldn't have a bad time at my girlfriends prom, she should be ashamed for being that clingy. It's so embarrassing!
I get you may be having problems with your relationship but you should communicate this with her. Instead of ditching her at prom it would be best to try to figure out your problems with her.
