They say time heals all wounds but Why cant I move on from the one that got away?!?

You already are moving on, we all are, we all go through what you are going through now. Hes always going to be in the back of your mind, pops up in your thoughts every once in awhile. But maybe you will realize he might not come back. Dont always think it will turn out okay. It most often wont, but always tell yourself this; I will hope for the best.
