Is it time to push him? Need help for depressed H

[summerd]

My husband is battling serious depression. I don't know whether he's on his medication - but the separation he thought might help has not made him any happier. Now I'm getting depressed and our son revealed last night that he's really having a rough time with all this. I got a life, I've layed off him almost completely - but the GREAT solution oriented therapist I'm seeing says it's time to try to get him to come home - that he doesn't need to be in his lonely "motel" like place during the holidays. This month is his b-day, our anniversary and halloween! She thinks this is all trauma induced from cancer 3 years ago and not a midlife crisis. When I told him this morning about the things our son said.. I added that, "we really miss you, honey." He could hardly speak during the conversation - he just cried and said, "I think I have to hang up now."
Should I take the advice of the counselor and just try to push him to come home??
