Query: 18 Years after reading this book

I read this book when I was 40 and had never been married. At 41, I started dating a man unlike anyone I had dated previously, and shortly before I turned 44, we were married. Last week we celebrated our 15th anniversary. I have found that a number of my friends who married for the first time after the age of 30 had read this book just before they started dating the men they ultimately married. This book taught us why we were attracted to men who weren't emotionally available, and how to be attracted to men who were.
