When my ex had a break from his affair partner he was a bit of a mess. I found his parner's phone number and they were afraid that I would get her husband involved. So they had a very short break.
Your H resembles my ex in that he doesn't seem to have anything that connects him to your family unit. You do the bills, take care of S and things around the house, what is left for him to do? Maybe it is time to let him pick up the slack. I have to boogie but will check in later.
