My best friend and partner of > 40 years up and left me 6 weeks ago today. She hopped in her car, and moved across the country to take up a new relationship and a new life in a new place. Ten minutes before we were about to have a large family dinner party - the guests were already on their way.

Our couples' therapist shortly thereafter recommended to me this book:

"The Journey from Abandonment to Healing", Susan Anderson

I have found it quite helpful, though it is a bit new-age in places and some of the material doesn't seem science-based. The parts that are, however, seem in line with the other research and thinking I have been doing.

Anyways, y'all may find it of some help.
