It is very interesting the contrast in our situations - you very seldom hear or see your X, and it stirs up strong emotional thoughts, whereas, I have to talk and see my X almost daily and I have little regret that we are no longer together. It may be that the time apart causes deeper thoughts of reflection for both you and your X.
You or anyone else should not be wasting thoughts on what the future holds for your X. Just realize what she is - a person that cannot live in a long term relationship. She lacks commitment.
There is someone else that will come along that will lift your spirits and recapture your heart. The new person will have their own flaws and qualities. For myself, it is difficult to not make mental comparisons, but the thought that sticks out most in my mind is that the one I am with now believes strongly in developing a life long relationship. You may be thinking that you wont find someone like what your X once was - dont look for and have hopes for finding such a person as it may only bring back memories. You have grown over the years and your tastes and interests have changed too. Keep an open mind and you may be pleasantly surprised someday.
