The Season 10 premiere of The Real Housewives of New York kicked off with a bang.

Luann de Lesseps got deep about her doomed marriage to Tom D’Agostino and even admitted to Dorinda Medley that cheating had played a big part in their divorce.

"I never thought we'd be here. But here we are — divorced," Lesseps said. "I loved Tom. I did everything I could to make this marriage work. But sometimes it's just not possible. Sometimes, love just isn't enough."

"He seemed to get worse after you got married." Dorinda replied and De Lesseps agreed.

The Countess then went on to describe the moment that haunted her most: when Bethenny Frankel gave her advice right before her wedding, telling her if she had any doubts, she shouldn’t marry him.

"I didn't want to see it, I didn't want to believe it. But after a while, everything the girls were saying was kind of true," de Lesseps told the camera. "Ultimately for me, the last straw was really the lack of respect. It just didn't end. From meeting up with ex-girlfriends every other day. From being caught kissing another woman at a bar. To being out all night and not coming home. It didn't stop, and I couldn't breathe. I felt like the water was just tumbling in and I couldn't keep my head above water. I suffered a lot. I mean I really suffered a lot."

"I couldn't stop this like merry-go-round of like the going out," Lesseps added. "I would go home and he wasn't home. Somebody would send me a picture and there's Tom out again. It just didn't stop!”

Since her divorce, de Lesseps and the rest of the RHONY ladies reunited at a Halloween party Medley hosted. Things got awkward when Sonja Morgan showed up to the party in an I Love Lucy outfit and avoided the ladies as she clinged to her new beau, Rocca.

"I don't get it. Sonja doesn't come over, doesn't say hello — Just sort of next level strangeness" blasted Carole Radziwill.

Morgan, however, had been MIA for most of the summer. She admitted that she had gained a lot weight, and all the heartbreaks she went through last season forced her to take anti-depressants.

"After so much drama and tragedy, I just had to get out. I went to Costa Rica, I was traveling," Morgan revealed. "I took anti-depressants and started stuffing my face with croissants."

Eventually Morgan made her way to the group after Rocca left the party. There she was forced to confront de Lesseps — who was dawning a controversial Diana Ross outfit — about the rumors she’d been spreading about her.

"When you said I was dating, I wasn't yet divorced," de Lesseps told Morgan.

"I thought it was fine," Morgan replied.

"No its not fine," de Lesseps slapped back.
