why do man cannot be contented with one woman?

well, man in nature is polygamous, mostly they are not contented with only one woman in there life no matter what you do to please him. But as long He still go back to her home means that he still love her wife more than the other woman. Just think it as a challenge for her to take, dont be to sad about it for man always go back to the original wife when he find out that she is one of a kind.

Hi Jarneck! Welcome to the site! I hope I could help your friend. Anyway, I would like to share something with you. I know some men like your friend's husband. My father was one of them. When we're younger he used to go the entertainment club with his cousins. They drink and have some ladies in their table. I don't know why he have to do it. I hated him so much. I could not do anything because he's my father. The good thing is that my mother extended her patience for the sake of her love and family. Until one day, this things ended as we get older. Maybe he realized the harm he have caused. If your friend love her husband maybe she needs to talk to him seriously about this matter. Don't nag at him, it could get worse. Try to tell him how you feel for it, how hard for her to accept this things as a wife. I know it would be hard to do but it's for the better.
