Question_I just read your article on Fox News about infidelity.The other day my sister-in-law and her circle of girlfriends, all divorced, were gathered at the beach house.One of them asked me why men cheat, as her ex had.My thought is greed, she an attractive, well built, intelligent woman, and a good mother.Like herself and her friends, her ex will never be satisfied.If he has a Mercedes he yearns for a Bentley, the day after he gets the Bentley he wants a Rolls Royce.What are your thoughts? Thanks, Ethan
