It is not surprising at all that you are fed up and frustrated b/c you've been doing all of the "heavy lifting" to save your M while H hasn't "lifted" a finger toward it.
You need to allow yourself some time away from being the "strong one" and let it go for a bit or you may end up so embittered that H won't stand any level of a chance.
To that end, H is moving, but his agenda is different than yours. See, his first hurdle appears to be his job, then his role as a father and a husband are well down the list. It seems as if that is how he's programmed to think.
He's so locked up and focused on work that he can't even think about anything else until that situation is settled. The good news is he took your advice and took some days off of work (something that would have never been an option for him in the not to distant past). Even though he slept, he did choose to come and sleep w/you. As FG said, he has comfort w/you. I know you want him to leave, but in his way, he seems to be moving forward.
The timetable for H is much, much different. He has a fragile psyche and low self-esteem (IMHO) and he's fumbling around trying to find himself. To him, he does see things as getting better - maybe b/c his work stress is starting to crystalize, but who knows?
I know that isn't what you want from him, but remember, you are (and should be) filled w/frustration b/c you've been the worker.
Do what you can to pull back from at least the psychological aspect of repairing the M for a few days to allow yourself to rest, relax and try to let some of your disappointment abate.
It is easier said than done, I know, but this may help you to reduce your stress and tension.
