"I try not to revisit that place too often, but when I think about his speech, I think of her face, her eyes, the hurt," Dupre said.
Her message to Silda Wall Spitzer: "I'm sorry for your pain."
Dupre, 23, said Spitzer was polite and businesslike when they met.
"Some guys, they want to have conversations and really get to know each other," she said. "With him, it clearly was not like that. It was more of a transaction. Strictly business."
Dupre said she practiced safe sex with her clients, including Spitzer. On her lawyer's advice, she would not elaborate on their liaison, or say whether Spitzer visited her more than once. She did say that he dressed casually, and she did not see his security detail.
Dupre also spoke with Diane Sawyer for a "20/20" segment to be aired tomorrow. In the interview, ABC said, she describes how an "upper middle-class girl next door got into the profession and the psychological journey she continues to experience."
Four people have pleaded guilty to running the prostitution operation. Last week prosecutors said they wouldn't bring criminal charges against Spitzer.
Dupre envisions her future in music, fashion, and writing books, but not prostitution.
"Never again," she said.
