Do NOT have her read the book. It is your guide as to what to do. You may very well be sabotaging your future efforts of DBing. She may think that everything you do from there on out is from the book and not from your heart. I say keep the book to yourself and in a place where she won't find it.
Telling a WAW to read a book is the same as telling her she is the problem. I doubt you are willing to do that. If you must suggest a book to her try Men are from Mars and Women are from Venus. There is some good info that help you two communicate. But keep the DB books for yourself.
