On the season eight finale episode, Bethenny Frankel presented photographic proof that the Countess' fiancé, Tom D'Agostino, Jr., kissed another woman at the Regency Hotel in New York.
"It felt like someone ripped my heart out of my chest," she tells People of seeing the photos. "I was devastated. I had my heart broken on television."
Despite his locking lips with another woman the night before the couple's engagement party (de Lesseps reveals they'd had a fight and parted ways), the reality star is choosing to move forward with her engagement.
"I'm not going to let a stupid kiss ruin the rest of my life," she says. "He screwed up. What he did was wrong. But this wasn't premeditated. It wasn't an affair. It was a mistake. He was upset with me. It was a stupid retaliation of some sort. He did the wrong thing, and he totally recognizes that. I know in my heart of hearts that he loves me."
D'Agostino Jr. also realizes that his actions were a mistake. He tells People, "If I could take it back, I would," and adds, "I deeply regret the mistakes I've made, and most of all hate the way it hurt Luann."
Though de Lesseps has made peace with her love's indiscretion, she says she would not tolerate history repeating itself: "Obviously, if it happens again, I would have a serious problem with that. Fool me once, shame on you; fool me twice, shame on me."
