Sounds like he's running from the pain and trying to escape or deny the depression. It feel lonely when my husband is doing this as he is now. It's like it's not registering with him that I don't want to go out with friends so instead of staying with me he opts to go alone. Then I feel bad for not feeling good enough to go. I feel if one is manic depressive we need the support here or at other places. So I am sending prayers and reminding you that only you know what is going on with you. Us manic depressives, know when the depression cycle hits and it's not fun.
