I don't think your H "feels this is where he belongs" either, but I do think he knows it at least subconsiously.
Yellowrose once told me that when her gut and DB conflicted, she always went with her gut, and she is a remarkable success story. You sound like your gut is telling you that you've had enough, at least for now.
Given that, I guess it's time to draw the line in the sand with your H and tell him it's time to fish or cut bait.
I wouldn't do it angrily. Try to just stay calm and reasonable if possible.
Take care!
