Or, instead of taking the time to listen to a book, how about using that time to, I don't know, be an adult couple and discuss any problems you're having?
We do sit down, listen and discuss. I think by listening to unbias advice from an educated professional, both our sides are being conveyed in a way that creates mutual understanding of what the other person needs. This alleviates power struggle when trying to communicate through arguments that may occur. We both take in the information together "as adults" then discuss both our perceptions on how we can implement the advice and be forthcoming in the future "as adults".
Not for everyone though...I on the other hand appreciate my friends suggestion for it- LOVE IT!
