Bren, you may also find this useful. This is a short interview with Shirley Glass, author of Not Just Friends. A landmark book on the subject of infidelity..
She spent twenty years researching that text. Michele Davis even endorses it on the cover... So I would think she would approve of much of the work done in the text.
This interview summarizes quite well a lot of key points in the text, but you can get the text on amazon.com, it was published in 2004 ...
