So much has been written on love and marriage and yet romance and commitment remain illusive. New research findings provide insights and strategies for success. The scientific explorations have focused on couples who are thriving and the skills they use in seeking and sustaining a relationship. Among the topics discussed include:

• The history of romantic love and the "grand experiment" in which we are all subjects.

• The one essential skill your partner must have for love to endure.

• Why passion leaves and how successful couples regain it.

• What is the healthy pain in relationship, how and when does the pain arrive and leave?
