I've been in that situation. In a situation like you describe, I don't think it is possible to have that sense of "closure" that you're looking for right away. There is going to be some emotional rawness for awhile. With time though it does get easier. At some time down the line, the whole thing recedes enough into the past to where you kind of close the book on it. In my case, I did end up moving to the next state, and that did really help break those ties that bind. Eventually, your life moves on, and this relationship will belong to history. But if you keep reconciling, then you just stay in that pattern and get nowhere.

If it hasn't been a good relationship, you'll eventually find that you don't miss it as much as you feel you will right now.
