A man who only has a network with his wife and kids does not make him an automatic great dad, giver or good husband. It just means you have closed your options off to a supportive network or might have fear for a deeper connection.

Could also mean your wife does everything and is stressed out. All my friends with husbands who have no friends are drained and beg for him to go and get a hobby or friends.

Comes back to the socialization of men as takers and women as givers. Not true across the board, but for the most part, very common.
