Query: Naive wife marries cheating man

This book was not even worth the time it took to read which was very quick anyway. I thought it was incredibly nuts that Kathryn didn't even notice over those 10 years that her husband was doing this, what world was she on? The characters in this book were very unbelievable, especially Mattie the daughter. Don't waste your time on this novel!
