Why would a 42 year old healthy unemployed male married with infant move in with parents
Why would a 43 year old healthy male. Married with an infant move home with mom and dad?
You would have to ask him. As he is unemployed, and I assume maybe can't pay his bills? Perhaps he can't think of anything else to do. Or maybe he feels overwhelmed and needs help. As I say, you would have to ask him.
