We're not talking Pokemon cards here, people don't read self-help books for storyline, it isn't Twilight or Harry Potter, it is a book about self improvement. Like I said, I agree to disagree with you both, I thought it offered some good perspective and will leave it at that.
I do agree that it won't help the OP, but I don't think any book will. He doesn't believe he is the problem in his relationship, so apart from bluntly beating good information into his head, nothing on paper is going to help him.
