Oh, I see where you are going with this. He didn't go to prom with his girlfriend though, so he didn't want to go back somewhere with the girl he went to prom with and do things with her since it would be cheating. I'm sure if his girlfriend was with him at prom, he would have hungout with her afterwards.
