Generally the divorce case takes place because you cannot satisfy the wife by sex. That is the psychology. That is the only psychology. Ordinarily, women, unless they will be satisfied by sex, they will not be faithful wives. This is women's psychology. So most of the divorce case takes place because the man cannot satisfy the wife by sex. By inquiry you will find. And because the husband mixes with so many other women, he cannot satisfy his wife. This is the psychology.
