There is a book called Beyond the Locket, which I hope othres here will find helpful.
Many times I didn't think anything was wrong with my children because they weren't dying, and I was to busy with myself and their mother (no names).
This book shows what we weren't considering through a story about a princess in medieval ages whose parents were also separating. Odd, I know, but the strangest approaches can make you see things in new ways.

THe book is endorsed by Dr. Pope, president of the ACA; Dr. Canfield, the President of International Association of Marriage and Family Counselors; and Richard F. Barry, the President of the America Academy of Matrimonial Lawyers. So it is not without recommendation
