On last night's 20/20, Jenny Sanford sat down with Barbara Walters to discuss her husband's affair and the subsequent toll the extremely public fallout took on their marriage and their children. Clip after the jump.

Sanford notes that the e-mails, which her children have read, were the final straw that caused her to leave the marriage, and that though Sanford has tried to reconcile with her, she is determined to get divorced:

When asked by Walters if she knows whether Sanford is still in touch with his mistress from Argentina, Sanford insists she doesn't want to know, because she wants to move on. "I would say that I have acted honorably in our marriage," she says, "and I've been the best wife I can be. But now I'm looking forward to whatever comes next."
