Oprah Interviews Elizabeth Edwards

Elizabeth says she encountered the other woman once at a political rally in Chapel Hill. "I didn't meet her really. One time, we were in the same place," she says. "I was with my family and children and my brother and sister, and she walked by into another area. ... And that's the extent."

At first, Elizabeth says she wondered if she did something to cause the affair, but she's come to the conclusion that it was never about her. Now, she holds John and the other woman responsible.

"I blame John, but also, women need to have more respect for other women," she says. "It takes a lot of work to put together a marriage, to put together a family and a home. ... You have to have enough respect for other human beings to leave their lives alone. If you admire that life, build it for yourself. Don't just try to come in and take somebody else's life."
