Husband is depressed, feeling clueless and hurt. Need some insight.

My husband recently came to me and said he's depressed and has been unhappy in our 10 year relationship. I'm doing my best to be patient and loving while he works through it, but he wants both to do with me. No physical contact. I don't know what I'm supposed to do.

We have a 10 month old baby. Part of me is beginning to wonder if he really doesn't want to be married, or be a father and the guilt is eating away at him.

He left at 6:30 to go to a game store and play some games to meet people. I was all for it if it makes him happy. But, it's 1am and he's still out. Is this really depression or a midlife crisis? I'm at a loss.
