South Carolina ? South Carolina Gov. Mark Sanford may keep his office, but he is losing his marriage.

First lady Jenny Sanford capped a tumultuous week by filing for divorce Friday, two days after state lawmakers stopped short of recommending her husband’s removal for a top-secret June rendezvous with his Argentine mistress. He will not say whether he is still in contact Maria Belen Chapur, the woman he famously called his “soul mate.”

Jenny Sanford, a former Wall Street executive who helped launch her husband’s political career, said Friday their 20-year marriage could not be repaired.

“This came after many unsuccessful efforts at reconciliation, yet I am still dedicated to keeping the process that lies ahead peaceful for our family,” she said in a brief statement released as her divorce complaint was filed in family court.

Her husband, who a day earlier told reporters he still hoped they could reconcile, blamed himself for what he called “the moral failure that led us to this tragic point.”
