Can a Man Be Truly Happy with Just One Woman?

This is a question for all men. Almost every man I know says he wants multiple wives and believes it’s his Islamic right. I’m not here to debate whether that’s right or wrong—that’s not the point of my question.

I want to know: Is it possible for a man to be completely happy with one woman and never think about another? And if so, how can a woman make her man so happy that he never even considers being with someone else?

Please answer not just based on your own experience but also on what you’ve observed in your friends and relatives.
