Drawing inspiration from Sandra Bullock, Elizabeth Edwards said she refused to become a wife who simply stood by her cheating husband. In an interview with Today host Matt Lauer that will air Wednesday, Edwards said, “I’m not just a cuckolded wife.” Edwards also said she still thinks she married a "marvelous man," but that husband John "changed over time.... He's no longer the person who I married." She also admitted to watching Oprah Winfrey's interview with Rielle Hunter, saying "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." Edwards announced her separation from husband John in January, after he admitted to fathering a child with Hunter.
