Now, David realizes he's "a very selfish person" and wants more discipline in his life. "I do want to be controlled because I'm not in control of myself," he says. "It's about pride for me. I've got a pride issue that I've got to deal with."
Since the affair, David has also had trouble reconciling his actions with his beliefs. "This has been a real moral bomb in my life. I'm a church-going, Bible-believing person, you know? Morally it hurts me. I said to my wife last night it feels like cancer."
