The only thing Elizabeth Edwards asked John Edwards for when they married nearly 30 years ago was fidelity, she told Oprah Winfrey on Thursday. "I wanted him to be faithful to me," Edwards said. "That was the one thing I asked for. I mean, I asked him for that. He willingly said yes." Elizabeth also revealed that John claimed that the affair started when Rielle Hunter approached him outside of a hotel with the line, "You are so hot." Elizabeth, who has terminal cancer, has a new book out describing her struggle to forgive her husband. (Photo: WENN)
