He does need to GAL. He can't rely on you to be his life for him.
Unfortunately most of the good advice books I've got, other than DR, have to do with affairs. You probably don't want to suggest one of those.
What about Dr. Phil's Relationship Rescue - would that be appropriate for him to read and think about? That was the first book I read and I spent a lot of time with it before I got DR. It doesn't focus on GAL so much, but it does have a lot of exercises for the individual to do.
