In an exclusive clip from the episode, Jennifer explains to consultant Debbie Asprea how she became ready to say “I do” to a man who’d already walked down the aisle.

Ellen reveals that a bout with Obsessive-Compulsive Disorder after the birth of her daughter left her repulsed by touch, which she felt was “unfair” to Peter.
He shares, “I never wanted to embarrass Ellen. and I never wanted people that don’t understand all of the details of our life, to know that I was lonely.”
Peter continues, “This isn’t really religious-based. We were all Catholic, [this is] clearly pretty far from the religion in which we were raised.”
Says Ellen, “This was something that I kind of pushed. I wanted to be sure that he was okay.”
