Overall, the book is an interesting read, a bit moralistic in tone but does show some insights into why affairs happen. Dr. Hein could have made it better by classifying affairs by type and avoiding the sterotypical assumption that affairs are motivated simply by unrestrained sexual desire. Personally, I would like to see more information on long-term affairs, and also a definition of what Dr. Hein considers "public" when discussing affairs.
Finally, I would have appreciated links to Internet sites that provide support for MP and OP involved in EMRs.
