She's moved on and the family that you once had is most likely gone forever. That is often a hard pill to swallow. Couple that with the fact that you haven't found the right person yet so your future is unclear. This is all normal and will fade in time. Unfortunately in this game of life there are no shortcuts. You will feel indifferent one day.
That certainly may be possible. I guess trying to deal with everything (divorce, moving, etc, etc), the thought of another guy in my sons life didn't cross my mind that often.
