Elizabeth Edwards: Whether She's in Love With Husband Is a 'Complicated Question'

Elizabeth Edwards, wife of former Presidential candidate John Edwards, breaks her silence to Oprah Winfrey, speaking out for the first time about the state of her marriage, her husband's infidelity and his former mistress' baby. She also speaks emotionally about her on-going battle with terminal cancer.

In an interview with Oprah Winfrey scheduled to air Thursday, Elizabeth Edwards said the question of whether she is in love with her husband and former presidential candidate John Edwards -- who admitted to having an affair -- is a "complicated" one.

On whether their marriage is a day by day thing, Edwards said, "Neither one of us is out the door, so I guess it's day by day, but maybe it's month by month."

Edwards is scheduled to appear on "The Oprah Winfrey Show" to talk about her new memoir, her husband's infidelity, her marriage and how she handled her bout with breast cancer. The interview was taped at the Edwards' 28,000-square-foot home in Chapel Hill, N.C.

It coincides with the release of her memoir, "Resilience," in which Edwards lashed out at Rielle Hunter, the woman with whom her husband had an affair. She called Hunter's life "pathetic," and also said that her husband, a former Nouth Carolina senator, should not have entered the 2008 presidential race.

As for how her husband's affair began, Edwards said Hunter, now 45, was the one who spotted and then approached her husband.

"What John said is that this woman spotted him in the hotel in which he was staying," she said. "He was meeting someone in the restaurant bar area, and she verified with someone who he worked with that it was John. John went to dinner at a nearby restauran, and when he walked back to the hotel, she was standing in front of the hotel. She said to him, 'You are so hot.'"

A Harpo spokeswoman told The Associated Press that the only caveat to the interview was that Winfrey could not mention John Edwards' mistress by name. Winfrey also spoke with John Edwards but excerpts of his interview were not provided.

In an accompanying article in "O" magazine, Edwards opened up about Hunter and how she was different from her own family.

"This person is very different from me, and really very different from him," she said. "We're basically old-fashioned people. So, this was a pretty big leap for him. Maybe it's being so different is what was attractive."

Edwards, who has three children from her 31-year marriage, told Winfrey she had no idea whether John Edwards was the father of Hunter's baby.

"And there is great speculation that your husband John Edwards is the father of that baby," Winfrey said.

"That's what I understand. I've seen a picture of the baby. I have no idea. It doesn't look like my children, but I don't have any idea," Edwards replied.

Edwards told Oprah she only asked John Edwards for one gift before they got married 31 years ago. "I wanted him to be faithful to me," she said. "It was enormously important to me."

Edwards Rips Husband's Lover in Memoir

Elizabeth Edwards has barely been seen publicly since last summer, when news of the affair broke, but that will likely change this month, when her memoir is published.

Titled "Resilience: Reflections on the Burdens and Gifts Facing Life's Adversities," the book was originally due to hit shelves May 12. But the publisher, Broadway Books, moved up the release date because excerpts had been leaked to the media.

In the book, Edwards revealed that she vomited when her husband first told her about the affair in December 2006, days after he announced his presidential candidacy.

"I cried and screamed. I went to the bathroom and threw up," Edwards wrote, according to the New York Daily News, which obtained an advance copy of the book.

Edwards suggested that Hunter, a video producer who worked for her husband's campaign, seduced John Edwards with the pickup line "You're so hot." Hunter was paid $114,000 for producing a batch of short films for the campaign.

Edwards apparently does not address the issue of who fathered Hunter's now 1-year-old daughter. John Edwards has said he and his wife believe he is not the father.

John Edwards first publicly admitted the affair in an August 2008 interview with ABC News' Bob Woodruff.

"It was a huge judgment, mistake in judgment," he said in the interview. "But yeah, I didn't think anyone would ever know about it. I didn't."

He also described coming clean to his wife. "She had to know it, and it was painful for her. Hard and painful for her, but she responded exactly like the kind of woman she is. And then she forgave me and we went to work on it."

Elizabeth Edwards' account, however, is a little messier. She said in the book that when her husband first admitted the adultery, he "left most of the truth out," saying it was a one-time fling.

'He Should Not Have Run'

Even when she knew the full truth, Edwards threw herself behind her husband's campaign. When her breast cancer returned in March 2007, she urged him to continue his run.

"One of the reasons that it's important, from my perspective, to move forward with this is that I'm immensely proud of John's campaign," she said at the time.

Lagging behind Barack Obama and Hillary Clinton, John Edwards dropped out of the Democratic race in January 2008.

Edwards writes in the book that she had initially wanted her husband to quit the race, because she was afraid the affair would raise destructive questions for her family, according to the Daily News.

"He should not have run," she writes.

Had John Edwards not run, some political strategists say that could have changed the outcome of the primary.

"If he had come out and dropped out of the race particularly early, I think a lot of voters would have taken a good fresh look at Hillary Clinton," said Mark Penn, a Democratic strategist who worked on Clinton's campaign. "Remember, they supported Edwards because they thought he was honest and trustworthy."

The couple were always thought to have a strong marriage. In a rare interview with the Detroit Free Press last fall, Elizabeth Edwards said the idea that they were a perfect couple was a myth.

"There is no perfection out there," she told the newspaper.

But the couple has weathered her two bouts with cancer and the 1996 death of their son, Wade, and also, it seems, the affair.

"I lie in bed, circles under my eyes, my sparse hair sticking in too many directions," Edwards writes in the book. "And he looks at me as if I am the most beautiful woman he has ever seen. It matters."

Edwards' Troubles Not Yet Over

John Edwards acknolwdged that federal officials are investigating whether any presidential campaign cash was used as hush money to keep his affair with Hunter out of the public eye.

"I am confident that no funds from my campaign were used improperly," Edwards said in a a statement to the Charlotte Observer. "However, I know that it is the role of government to ensure that this is true. We have made available to the United States both the people and the information necessary to help them get the issue resolved efficiently and in a timely matter. We appreciate the diligence and professionalism of those involved and look forward to a conclusion."

Edwards' senior political adviser Joe Trippi told ABC News that the former Democratic candidate should not have run for the presidency.

"There is no doubt that he changed the race on the war, on healthcare and on challenging special interests and lobbyists." Trippi said. "But even with all that, he probably should not have run."
