Why would a married man flirt with another girl?

Anonymous
Why a man 38 years old tends to flirt with another girl who is 27 years old, even if he is married. He has a beautiful wife, is it mean they are not compatible or there is just nothing right in their marriage. So he attracts to other girls. Or he finds the qualities he wants in another girl, which are not there in his wife?
