Jenny Sanford Speaks Her Truth

Through the ordeal, Jenny says, she hasn't lost sight of her children. She says she told the boys about their dad's affair when he was in Argentina. "My gut was right that perhaps he was seeing this woman and I felt they needed to know," she says. "It was painful for me to tell them. They had always held their dad in very high esteem."

Jenny says she told all four boys at the same time. "At the time we were separated, I had asked Mark to leave the house, and I had also asked him not to talk to us...And they were having a hard time with that," she says. "I said, 'Here's why you can't talk to him. Your dad's been having an affair.'"

Jenny says the boys had mixed reactions. "One of them said, 'I guessed it,'' she says. "But the other one, said, 'Huh?' One of them asked, 'Did they have sex?' And they were shocked. Their world as they knew it was changed."

Since the boys found out, Jenny says there have been good and bad days. "It's safe to say we've had a range of emotions. Some days they're just grumpy. And you know what? They have a right to be," she says. "I would rather us embrace it and learn from it and make sure we don't make the same mistakes in our lives going forward."
