Query: the only book I have ever reviewed - extremely effective

I have been struggling with a lack of intimacy for many years. It cost me the woman that I had loved for 15 years. This book helped me understand why and how I failed to create that intimacy - and gave me a real plan for attacking the problem. Real solutions that I could use, AND I AM A GUY...... My copy is dog-eared and almost unreadable because of the highlights and underlines and turned down pages. It has enabled me to approach a new life with new women, helping me to create the intimacy base necessary for a full and rewarding life. THIS IS THE BEST BOOK I HAVE EVER FOUND ON MAKING A LONG TERM RELATIONSHIP WORK - AND IT MAKES SENSE TO MEN...........
