(CNN) - Rielle Hunter said Tuesday that she and John Edwards, the former presidential candidate who fathered her child in an extramarital affair, have gone their separate ways.
"We are a family, but as of the end of last week, John Edwards and I are no longer a couple," Hunter said on ABC's "Good Morning America."

Her announcement comes the same day she launches her tell-all book about the relationship, 'What Really Happened: John Edwards, Our Daughter, and Me."
It also comes nearly two weeks following the Justice Department's decision to drop the remaining charges against Edwards over allegedly violating campaign finance laws to cover up the affair. The Justice Department decision came after Edwards' corruption trial ended in an acquittal and mistrial last month.
In August 2008, Edwards admitted to an affair with Hunter, a onetime videographer for his Democratic presidential bid. At the time, the former North Carolina senator denied paternity of the daughter she had given birth to six months earlier.
While Edwards and Hunter were seen together in a series of beach photos last week, Hunter said their relationship had now fallen apart–a decision she described as mutual.
"For my part in it, it's because I'm no longer interested in hiding, hiding our relationship, not living out in the–"she said, stopping herself. Saying the couple "had a lot of media scrutiny," Hunter added their situation was "complicated."
"It's hard, and it wears you down after a while," she said.
While she regrets "many things" in their romance, she argued she does "not regret loving him."
"We have lots of things to figure out," she said, referring to their four-year-old daughter, Quinn.
Responding to intense criticism over her new book, Hunter defended her decision to release the title and insisted she wanted to come out with her side of the story.
"There's so much misinformation and distortion and spin about this story, and people form opinions without knowing what really happened," she said.
