After more than 20 years of marriage, "Real Housewives of New York City" cast member Ramona Singer has split from her husband Mario Singer. The reality star ended things, after months of struggling following reports that he had an affair.

“I have decided to move on with my life without Mario. I tried my best to make my marriage work,” Ramona tweeted to her 423,000 fans. “I am excited for the new chapter in my life.”

The news comes after the "RHONY" reunion, when she flipped out on Andy Cohen and the ladies when they brought up her marriage troubles, which were made public in the fall of 2013 when allegations of her husband cheating came out of the woodwork.

Andy asked during the reunion what Ramona has learned through the ups and downs of their relationship.

“We all learn something new everyday. I’m saying, ‘I learn something new everyday,'” she responded with an eye roll. When Andy then asked again, she got angry.

“I have already answered your question, I learn something new everyday. I don’t want to take this any further, I have a daughter, that’s enough. Thank you,” she said, before turning to Andy. “So how’s your love life? Who are you going to have sex with tonight? Tell me,” she said.
