GrandTea your earlier post made me chuckle.

I think you need to have a frank and open discussion with your husband, no recriminations but just try to get to the bottom of the problem. There are any number of things which can make him feel unhappy and of course you will be in the firing line for his complaints. If he won't respond to you maybe one of your children could find out what is troubling him.
I have the opposite problem, my husband is relentlessly cheerful in the mornings and it drives me mad. I just want to be left alone with my coffee and the paper. We are never satisfied are we.
