(CNN) - Jenny Sanford, the wife of South Carolina Gov. Mark Sanford, said Friday she is filing for divorce.
She said in a statement that "the dissolution of any marriage is a sad and painful process."
"This came after many unsuccessful efforts at reconciliation, yet I am still dedicated to keeping the process that lies ahead peaceful for our family," the statement said.
The Sanfords have lived apart since June, when the governor admitted to an extramarital affair with an Argentine woman.
The governor's office did not immediately respond to a request for comment on the divorce filing.

After Mark Sanford made a nationally televised admission about his affair, there was a flurry of calls for the governor to resign and multiple investigations by media organizations and the state Ethics Commission into whether Sanford tapped taxpayer resources for personal use.
In November, the South Carolina Ethics Commission charged Sanford with 37 violations of the state ethics code.
The commission will hear arguments involving those civil charges from Sanford's legal team early next year. The state attorney general is still evaluating the ethics complaint to determine whether criminal charges should be pursued.
Several Republican state legislators drafted an impeachment resolution against Sanford, accusing him of "dereliction of duty" for disappearing from the state last summer without informing his staff or the the lieutenant governor.
But that measure was essentially killed by a special House Judiciary Subcommittee on Wednesday, which instead recommended censuring the governor for his behavior.
Sanford has said repeatedly that he will not step down from the state's top office.
Jenny Sanford's full statement:
Statement from First Lady Jenny Sanford
Columbia, S.C. – December 11, 2009 – 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. Because Mark and I are public figures, we have naturally had less privacy with which to deal with our difficulties than do other couples. Indeed, I know it will soon become known so I choose to release this brief notice that I am now filing for divorce. This came after many unsuccessful efforts at reconciliation, yet I am still dedicated to keeping the process that lies ahead peaceful for our family.
I remain thankful to so many across this state and nation for their words of encouragement and prayers during this difficult time. Please know the boys and I are doing well and are blessed with the incredible support of friends and family and bolstered by our faith and the unfailing love of our God above.
Update: In response to the announcement, Gov. Sanford released a statement Friday taking "full responsibility for the moral failure that led us to this tragic point."STATE OF SOUTH CAROLINA
OFFICE OF THE GOVERNOR
MARK SANFORD, GOVERNOR
Columbia, S.C. – December 11, 2009 – With regard to Jenny's public statement, Governor Sanford had the following to say:
"While it is not the course I would have hoped for, or would choose, I want to take full responsibility for the moral failure that led us to this tragic point. Jenny is a great person, and has been a remarkable wife, mother and First Lady. She has been more than gracious these last six months and gone above and beyond in her patience and commitment to put the needs of others in front of her own. While our family structure may change, I know that we will both work earnestly to be the best mom and dad we can be to four of the finest boys on earth.
"I will join with her in asking the press to respect our shared desire for privacy as we quietly move forward. We respectively ask for your prayers."
