"I don't live with regrets," de Lesseps told host Wendy Williams. "I mean, it was a part of my life that I was in love."
"It was a beautiful wedding," she explained of keeping her wedding photos on social media.
"I don't regret it. I don't take the pictures down, I'm not that kind of person. I don't, you know, live in the past. It's part of my life and that's how I live."
De Lesseps announced her intent to divorce D'Agostino in August after seven months of marriage.
The split came after months of the reality star defending D'Agostino amid rumors he was unfaithful.
"I have been defending Tom for the last two years," de Lesseps said.

"I stood by my man because I loved him. So it was really rough. It was a rough thing to go through. When you love somebody, you know, you have your blinders on."
"He just couldn't give up his bachelor kind of lifestyle," she explained. "The last straw was just between the women, the press, him going out. Me getting phone calls, pictures of him at the same bars, which I asked him not to go to."
D'Agostino told E! News in September he was "very sad" about his split from de Lesseps.
He downplayed the rumored reasons for the breakup, saying, "The publicized reasons for the divorce make for a great reality TV storyline."
