Ultimate Betrayal

Lynne admits that during the course of her affair, she was delusional about what was actually happening. "You choose to believe what you want to believe," she says. "You choose to believe the one person who is lying to everybody else. But you believe he's telling you the truth. I can look now and it's like, 'Duh.' But you just don't think of that at the time."

Lynne says she told lies, too. His wife called her once asking about some rumors she'd heard about the affair. "I said, 'Oh, no, no. We're just really good friends and sometimes people at work think it's more than that because we're really good friends,'" Lynne says. "I wanted to tell her so bad. I wanted to just say, 'You're right!' I wanted her to find out because then he would have to make a decision."
