Trusting, It sounds as if he has generally followed through on obligations (not without fighting, though). If that's been the case lately, he might just need a little paperwork catch-up time.
Trusting, I am a little worried when you say you aren't sure what to do when the kids are not there. I love D, but I sure feel the opposite--I have so many things I want to do and have no time to do because I am focused on her and making sure she does work for school and her activities and all that. I try hard to be a good parent and I know you do, too. But I do miss the time to myself.
There will be a point when they leave us. Make sure you are OK with Trusting and have the hobbies and interests to keep you happy. Not just busy, but happy. I understand what it means to miss them but it is so important to be happy with yourself and who you are. That is an important lesson I learned here.
