I think you're doing a great job so far. It sounds as though H is really thinking this through. Just keep up what you are doing.
As for feeling you're not there for your kids, I know how you feel. I'm going to set up some mini-goals for myself to spend more time with the kids. Ever since the separation from my H I feel like I've been putting all of my energy and thinking in trying to get my H back. Now I want to spend more time with my kids and let them see how happy I can be with "dad."
Be strong, I'm sure the next few weeks will be one hell of roller coaster ride.
