A Couple on Edge

To help further help Wendie and Tony fix their relationship, Oprah calls on relationship therapist Dr. Harville Hendrix. "I think you would have such amazing breakthroughs that it would absolutely change the way you see each other and yourself," Oprah says. "He's the best I've ever seen."

Dr. Hendrix is the founder of the Imago Relationship Theory, which he says is a way to transform an "unconscious relationship" into a "conscious partnership."

"[Imago] helps couples understand how the problems they have in a relationship in the present are connected to issues that are left over from childhood," he says. "Most of the stuff that's going on in a relationship has its roots in the past—we say about 90 percent in the past, and it's triggered by about 10 percent of the behaviors in the present."
