Welcome to piecing, Lyn. I know you've been on the BB a while as I recognize your "handle".
I'm sorry things are soooo incredibly rough for your H (and you) right now. It sounds to me like he's depressed. Could be a brief reactive depression due to these acute stressors, or it could be the more pervasive kind many of our spouses (and some of us) have experienced.
Definitely do check out some of the threads here. Lots of ups and downs, but TONS of inspiration too.
