Oprah: Do you think you hurt Elizabeth Edwards?

Rielle: I think Elizabeth has been hurt by this whole process. I think Johnny's been hurt by the whole process. I think everyone in his family has been hurt by the whole process.

Oprah: That was really good, but you didn't answer that question. Do you think you hurt her?

Rielle: Do I think I hurt Elizabeth? You would have to ask Elizabeth that. I don't know. I don't know the answer to that.

Oprah: Do you regret being a mistress?

Rielle: No, because I learned a lot. It went against every part of who I am and everything I believe, but I learned so much from it. So I don't regret it, [but] I would not repeat it.
