How to get over a relationship that never happened?

So a year ago, I reconnected with an old friend of mine who lives a couple hours away from me and we became really close. We talked everyday and eventually I developed feelings for her. The thing is, I never told her because one, I m a girl (she probably wouldn t see me like that), and two, she had feelings for someone else -a guy. Anyways, I realized later on that (obviously) the feelings were one sided -which doesn t make sense because I swear I sensed something from her -and so I started distancing myself away from her and we ended up not speaking and I haven t spoken to her since. Recently, I found out that she just got into the same college I will be attending this fall and I don t know what to do. A part of me thinks my old feelings are coming back and that I ll have a second chance at her, but another part wants me to just get over her. How do I do that and what do you think I should do?
