After Tammy learned the fight between the couple was a staged experiment, she wrote an e-mail to Oprah explaining her decision to intervene. "I've come to realize that when I don't walk through my fears to do what I believe is the right thing, I actually feel worse because I will beat myself up about it for days, weeks, maybe longer," Tammy wrote. "When I am able to face my fears, I feel better about not only myself but the outcome of the action."
