Elizabeth Edwards: 'I Knew I Could No Longer Be John's Wife'

Former Senator John Edwards' wife of 32 years, Elizabeth Edwards, is speaking out for the first time since their separation, in a visit with Matt Lauer on "Today."

Last year, Elizabeth told Lauer that despite her husband's affair, she still believed she married a "marvelous man." Today Edwards still believes that, but adds, "I think he changed over time. I think it was sort of hard for me to see it or admit it for a very long time. But he changed. Maybe we all change over time. And he's no longer the person who I married. I still admire an enormous number of things about him. The things he cares about are things I think are important."

Lauer then asked Edwards whether she watched John's mistress, Rielle Hunter, on "Oprah," where she spilled all the details about their affair.

"At first, I didn't watch it. And then I thought, 'Well, that's silly,'" said Elizabeth. "I didn't watch the whole thing. But I did watch some of it. I still think this person is so completely unlike me that it's hard to imagine the same person could marry me and be attracted to that woman as well."
