I came cross this article and just had to post the link. It's about why depressed men leave and is written by a man who shares his own journey with depression and destroyed marriages. Within the article are three links to his earlier segments. Make sure to read all of them.

It's one of those articles that makes my heart race as it so completely describes my H and what I perceive his inner turmoil to be like. After reading it I want to take action to fix him and us, but as the author points out there is nothing that a spouse can do. I will just continue to thank God for more understanding and ask that I continue to remember the man who is hurting and not focus on the behavior that causes so much pain.
