Hope, Sounds great. Really. He must miss you terribly. And maybe he's getting to a place where he's working through his own hell. And you sure as hell have.
As for what to do about being friends vs. not, do exactly what you're doing. Nothing. Just wait it out. See how it all plays out. It could be that you and your H needed to go through your own journeys in order to come back together. Or, it could be that you each went through your own journeys to end up with someone else. Either way, one thing is for sure... you will one day end up in a healthy, great R - whether with your H or not. That is becuase you have worked on YOU. You are whole. And you are fabulous.
Anyway, it sounds like a positive step. And as long as you can still focus on you (and no, that is not selfish), then you're in good shape!
You rock, girlie.
