I hadn't heard of alexithymia before, but it does sound like him. He hurts, but he doesn't communicate it. The only difference I can spot is, the article says people with alexithymia tend not to have an imagination, and that doesn't describe him.

I wonder if there is something going on in the environment. Nephew who lives with us has just told me he's in the throes of a depression too. So am I, and obviously so is my husband. We're all operating on an impairment here.

Hubby is the same way about back pain, which I didn't know he had until recently. I wish he'd ask for help, but because I have physical disabilities, he'd felt obligated to do the chores himself without telling me he was having any problem. Well, if something is too much for one of us alone, a lot of times we can work together as a team, and get it done without hurting ourselves.
