A friend told AP on Sunday night, Broadwell regrets the damage it has caused her family and that of Petraeus who resigned following the revelations more than a week ago.
The author is determined to repair the damage and move forward, the friend said.
Last night, her husband, Scott, appeared to be standing strong with his wife who moved back in to the family home after a week holed up in her brother's house in Washington, D.C.
WSOC-TV captured Broadwell returning to her Charlotte, N.C., home, welcomed by neighbors.
Broadwell, whose face was hidden by large, dark sunglasses, and her husband each carried one of their sons in their arms, and neither showed any emotion.
Asked for a comment, she remained silent and non-reactive.
Scott Broadwell indicated to a cameraman the family would have a statement "sometime soon."
Broadwell is still under investigation by the FBI in relation to classified documents found on her home laptop, which investigators believe the author obtained while researching her biography of Petraeus.
Meanwhile, Petraeus has hired a top Washington, D.C., lawyer, Robert Barnett, known for negotiating book deals for President Barack Obama and Sarah Palin, ABC News reported.
