You are going through a really tough patch at the moment, and doing very well. This is where my theory of them needing an event to snap them out of their current mood kicks in. Sounds like he has the black dog of depression visiting right now too, maybe read up on that a bit? Exercise would be ideal, but anything to change his head space will do it.
Clearly, you are not going to be that person, well directly anyway. However, where there is a will, there is a way. Could you get the kids to involve him in something he would enjoy? I actually got our closest couple friends (who were sensitive!) on the phone and asked the bloke to please invite H out for preferrably sport, but anything would do as he was feeling blue with life at the moment - please dont take no for an answer, and keep doing it for the next couple of months. This REALLY helped, not just cos it did get him out of the house a couple of times, but also cos it was not just me trying to fix things, you know what I mean?
If you cannot shift him at all, take off to a friends sudden emergency for a couple of days to recharge your batteries.One hours notice, no time to sort anything, just jump in the car and GO (Thelma and Louise style!)
Just aim on getting through his break best way possible for you.
I did notice my H was like this during his depression type phase, it seemed to indicate his replay was coming to an end and he was moving further down the tunnel. H was actually very very down, ended up going away for a weekend getting really smashed, thought about topping himself for the first time in his life, kind of bottomed out then moved forward.
For yourself, stuff like funny movies (good for the kids too), upbeat music, wine, exercise with dog etc wine!. Vent away heaps too.
