Is it safe to say that unless both spouses care enough to read the book, put into practice its principles and do something about the unhappiness that nobody is going to be happy?

Whatwillbe, please think twice about what you said about not staying faithful. Its a hard road to travel. Has your H read the book? Seems to me the most frequent thing I hear from most is the ability to get the LD spouse to even realise there is a problem. And then to get the LD to do something about it Would seem to me if the LD acknowledges a problem and agrees to compromise the HD has to be willing to do the same thing. Compromise. Isn't that what marriage is all about? Anyway, just my thoughts.
