I think it's not healthy for a child to see his father not interested in their mother or the family. I know children are sensitive and can feel things early on between the parents. Like you can feel tension between two people who have been arguing.

But, here it's like the people have accepted their roles in marriages. :sad:

I am only guessing here but, since a majority of fathers have their second life outside the family home. The mothers become independent from them in sleeping arrangements.

I do want to recognize the young Japanese fathers who seem to be more family oriented. I know they are few .
