He is depressed but you know that. Is he at least doing the Mr. Mom thing around the house? That would help if he at least took over the kids and house work. That is the tuffest job I ever did and loved it. Have him take care of the family. He will not have a choice. He has to get up and get the kids to school. Make sure the homework is done. Go on field trips. Bake cookies for a class project. Make dinner grocery shop. Clean the house. Do the laundry. Go to back to school night. And all that stuff. He won't have time to think of his failed business and will give him a new purpose that he has had all along but maybe not seeing.
Just some toughts.
