Don't beat yourself up about the book. In hindsight, I think most LBS's can see the signs they should have missed, along with the point their spouse stopped trying.
I found a book like that, too. My W was reading the book by Dr. Phil's wife, Robin. She stopped reading when she got to the chapter on doing what makes your husband happy. It's still bookmarked right next to the bed, where it has laid for a year.
