What amazing relationships have you seen?

A couple in the neighborhood got married early, both in their early twenties, and gave birth to a child. Their relationship has always been bad. The man works outside and the woman takes care of the children at home. Men rarely come back, almost once a year, but they earn money back every month. In fact, the man has a mistress outside, and the woman knows it, but she also acquiesces. I haven't divorced yet, waiting for the man to come back.

This situation is hard for me to understand, that is, the woman is not independent enough, but this was a generation ago, and the concept is different now.
