So today I found out one of my friends asked one of my old crushes to our winter ball(formal dance). It's been a while since this girl and I have talked, and even though I don't like her anymore, she's still in my system, like fat I need to get rid of. It doesn't bother me that he asked, but it bothers me that they're going together. I guess I need this, but I can feel myself yearning for her. I just need to get this off my chest before I do something stupid. Any advice on how to move forward from this? The girl and I e are in the same friend group so I see her a lot. I want her out of my system, but I keep slipping and I fall for her a little occasionally.
