As a carer I know where your hubby is coming from to a degree. A few times in the past my wife has got "Happy" like you did. But it always has been at the worst time for me. I am either very tired, or busy with something like the bills, or like just now. I am down here typing and my wife wanted to talk about something. I told her I'll be done in a few and heard noticable disapointment in her voice. I am still trying to find a way to deal with stuff like that, but don't feel bad. It happens, rather then be upset at it be glad you did have a moment of time where life was good for you. And keep the hope alive that more of those times will happen.
