You know, what you and your H are doing sounds kinda like what my XW and I did, with some major differences. I tried to listen to my XW and do things she mentioned, she just rarely brought other things up. Funny how many things she wanted to do after we split up.
I think you're on the right track. Let him go, and see what he does. If he doesn't put forth the effort now, he won't put forth the effort later.
