Quote: Personally, I believe he's suffering from depression.
Yeah, and that can really affect your drive - even my HD hubby took a turn for the worse when his depression was bad.
I'm still pondering writing a manual for the stealth treatment of the depressed spouse Since you're not living with him, you probably can't get him to take vitamins or exercise regularly (although maybe you could invite him along on some outdoor activities?). But maybe for a housewarming present you could buy him one of those "dawn simulators"? It's an "alarm clock" that works by gradually increasing to a very bright light in the morning. They are used to treat seasonal affective disorder but research suggests that light therapy can also help regular depression as well. He wouldn't have to know that's what it's for. Just a nice housewarming gift (If you get one, make sure it's one made for SAD, with a strong enough light.)
