Jenny Sanford, the estranged wife of South Carolina Gov. Mark Sanford, announced she is filing for divorce following his now-infamous affair this summer.

Mark Sanford admitted an extramarital affair with Maria Belen Chapur, an Argentinian woman, after flying down to see her in secret (he thought) in June.

In August, Jenny Sanford moved out, but said she still hoped to reconcile with her husband, with whom she has four sons. But those efforts were in vain.

"As so many of us know, the dissolution of any marriage is a sad and painful process. It is also a very personal and private one," she said in a statement.

"Because Mark and I are public figures, we have had less privacy with which to deal with our difficulties than other couples. I am now filing for divorce."

Jenny Sanford couldn't get past her husband's cheating and lying.

"This came after many unsuccessful efforts at reconciliation, yet I am still dedicated to keeping the process that lies ahead peaceful for our family.”

Once considered a potential GOP presidential contender for 2012, Mark Sanford refused to comment on Jenny's divorce filing earlier this morning.

Mark disappeared for several days in June, saying he was hiking on the Appalachian Trail. It turned out he flew to Argentina to be with his lover.

His tearful confession when the tryst with Maria Belen Chapur became known shattered his political career and nearly led to his impeachment.

If they couldn't make it work with after one affair, that doesn't bode well for Tiger Woods saving his marriage after racking up a list of mistresses.
