Thanks to both of you for replying so quickly and insightfully. As far as me - I'm actually doing pretty well. I'm back into my routine of hanging out with friends and being active, and both keep my mind in a good place. Now that I've really understood that a relationship just isn't possible now, I've stopped the constant obsessing of what-is-he-doing, is-he-alive, etc, etc. I do still think about him a lot, and more than anything just wonder how his life will turn out. I'm guessing he wonders the same thing. Honestly, as much as I miss him, life is much less stressful on a day to day basis now that we aren't talking. It would be awesome if someday sooner than later he was able to get his life together, but that's not where the wise money is.
Thanks again for the insight. I can think about him/us rationally for the most part, but there is still that 1% of me that has a strong emotional reaction.
