Ramona Singer is ending her marriage to Mario Singer, just a few days after part 2 of the Real Housewives Of New York reunion aired.

The couple have been under immense strain ever since reports emerged Mario had been cheating on his wife of 20 years with a much younger woman.

Ramona announced the news via Twitter, saying she tried to make it work but couldn't:

"I have decided to move on with my life without Mario. I tried my best to make my marriage work. I am excited for the new chapter in my life."

This is interesting considering Ramona absolutely positively REFUSED to talk about her husband's possibly infidelities on the reunion show, even going so far as to challenge Andy Cohen and insult him.

Ramona and Mario have one daughter - Avery, 19.
