Despite the split, she is remaining “optimistic” with the help of her two children: daughter Victoria, 22, and son Noel, 20.

Although the Bravo personality is working on “reconnecting” with herself, she isn’t closed off to love — and potentially marriage — in the future.

“I choose to see the good in people, not the negative,” says de Lesseps. “I’m shamelessly optimistic. As for getting married again? Never say never. But I’d definitely be more cautious next time.”
