This belongs to each person's point of view and each individual has a different perspective.  If now we stand from the perspective of a person who is wholeheartedly devoted to her husband and children, who doesn't care about anything, the fact that a husband has a lover leaving his wife and children should go and find a new happiness alone.  From the perspective of controlling people who always force their husbands to follow, maybe they will never give up on their husbands, even if they have a boyfriend or run away, they will still find and bring them back.  As for real life, each person has a situation and a fate that no one can live, so only the people involved know what is best for them.
