It is a private topic, and it is really up to individual to decide what to do and how to do it. This is really a cultural difference here. In West society, most couple do respect marriage and long term relationship. However, if a man or a woman decide to have an affair with someone else, they will not chase after him or her to save the relationship. Because it means that the husband does not love his wife as much as usual, once he decides to have a mistress on the side. It is better to save yourself instead of saving a marriage. Be financially independent is better than be dependent on someone else.
