Infidelity is a modern day reality. The truth remains that it was thought that it only affected the men.
But increasingly many women today are not as faithful to their husbands as they earlier were. The women know how to handle it as they always were for generations handling it. Men just simply don't know how to handle it.
Studies have shown that men are emotionally less capable of handling a scenario where the wife has a relationship outside of marriage. Also women fight it out at the emotional level and seem to understand men better. Women also can sense when a man is looking out in a marriage much easily.
Men are more of the belief that women have sex only when in love whereas the fairer gender believe that sex happens for men even when they are not in love. Probably, this very understanding puts women at a higher pedestal while dealing with men.
