But for the married Broadwell, 40, who was both biographer and mistress to former Central Intelligence Agency Director David Petraeus, 60, the revelation of the affair and subsequent attention has made her emotional.
"She's been devastated by this," Paula Broadwell's brother, Stephen Kranz, tells PEOPLE in an exclusive interview. "She is filled with guilt and shame for what she's done and she's incredibly sorry for the pain she's caused her husband, her family, Petraseus's family. She accepts responsibility for her actions and knows she made a mistake."
"Now [she] is really focused on repairing and protecting her family and trying to really focus on her husband and her children and protect the kids from this," Kranz adds.
And a source close to the family tells PEOPLE now that they're home, "They just want to focus on their family and get their lives back to as normal as possible, particularly for the kids."
The Broadwell family is also grateful for their friends, the source adds. "They're overwhelmed by the outpouring of support," says the source, who adds, "They're doing well right now."
Meanwhile, Petraeus has hired Robert Barnett, a Washington, D.C., lawyer whose clients have included President Barack Obama and former Alaska Gov. Sarah Palin, for "advice on post-governmental issues."
