thanks ladies
Fortunately DH managed to get outside in the weekend and did some 'manly' stuff around the block - by the end of Saturday he was much more like the healthy happy man I love. He recognises that he needs to do more of that just for his own sanity. A really nice bonus for me, apart from him cheering up so much, was that he became much more supportive and volunteered to do things that normally I've had to ask and ask for.

So hopefully he can keep that up, and I can focus on keeping my own sanity in line :-)
