Most Helpful Girl
In order to get over him you first have to cut off contact completely. There is no use of waiting for him to text you or contact you, because its only going to hurt you more the longer he doesn't. It
seems like a big mind game to me. He was trying to make you jealous, and the picture should tell you that he's moved on. In my experience of dating I've learned that no matter how many times you get together with an ex, it will no longer be the same because you DO change,and your outlook of the person changes as well.
You might think you want him now hun, but trust me you are better off focusing on school and your life. Boys and girls your age aren't looking for anything to serious now anyways, there is plenty of time to find someone new. :)
