"Mark is not a bad person," she says of her husband, South Carolina Gov. Mark Sanford, in an interview with Vogue magazine hitting newsstands this week. "What the world saw in that press conference is someone who is struggling. None of us are perfect. We are all trying to do the best we can."
Despite her acknowledgment of her husband's imperfections, Sanford makes clear in the interview that divorce remains an option. Two weeks ago, she moved out of the governor's mansion with the couple's four boys to spend the upcoming school year in the Charleston area.
"I have put my heart and soul into being a good mother and wife," she says. "Now I think it's up to my husband to do the soul-searching to see if he wants to stay married. The ball is in his court."
She said the man who carried on a year-long affair with Maria Belen Chapur was not the man she married. "It never occurred to me that he would do something like that," she said. "The person I married was centered on a core of morals. The person who did this is not centered on those morals."
Sanford said her husband's relationship with Chapur was almost like an addiction.
"Over the course of both pastoral and marriage counseling, it became clear to me that he was just obsessed with going to see this woman," she told the magazine. "I have learned that these affairs are almost like an addiction to alcohol or pornography. They just can't break away from them."
Sanford says she feels sorry for Chapur. But the Vogue piece also reports that Sanford said of Chapur after looking up a picture of her on the internet: "She's pretty."
"I am sure she is a fine person," she says of Chapur. "It can't be fun for her, though I do sometimes question her judgment. If she knew the newspaper had those e-mails back in December, why did she want him to come in June? But I can't go there too much. All I can do is pray for her because she made some poor choices. Mark made some poor choices. A lot of people were brought down by this, and I am sure that is not what they wanted."
Sanford says her husband - currently on the defensive after reports that he flew in style overseas on the taxpayers' dime and used state aircraft for personal use - "has got some issues that he needs to work on, about happiness and what happiness means."
"You wish it wouldn't come to a crisis like this, but I think when a lot of men get to this midpoint in life, they start asking questions that they probably should have asked a long time ago," she says.
"Midlife aging is different for men than for women," she says. "Mark is worried about what his next job is. He worries about making money, running for office again, his legacy. I know my legacy is my children. I don't worry about that."
