I recommend The Way of the Superior Man (http://www.amazon.com/Way-Superior-Man-Spiritual-Challenges/...). My roommate lent it to me after an ugly breakup. The title is a little silly (I certainly wouldn't describe myself as "spiritual") and I don't agree with every word of it, but after reading this book I finally felt like I understood women and relationships, and I met my now-wife a few months after reading it. I doubt I would have gotten her without it.
