You don't think he's maybe upset about losing his job? I've shared on this board before that when I lost a really good job 3 years ago, I was devastated. I took a shot to my self-esteem that didn't go away til 4 months ago (yep, my wife divorcing me woke me up, ironic eh?)
Can you reach out to him and see if he'll share his feelings on the job situation? Don't blame, don't accuse, nothing negative (no eye-rolling) and see if he'll open up a little. Chances are if you give him a safe place to talk about it, he MAY open up a little. Maybe give you a glimpse of what's going on with him.
Or, he might do what I did, bottle it all up, convince himself everything will be good again, and try to "just move on." Yeah, that didn't work so well. And it's a damn shame, as I know my wife would have been there for me, no doubt. I was such a putz.
We can talk ourselves into defeat or we can talk ourselves into victory - we are creatures of our thinking.
