Ramona Singer has announced she's splitting up with Mario for good, she revealed on her official Facebook page Thursday.
"I have decided to move on with my life without Mario," she wrote. "I tried my best to make my marriage work. I am excited for the new chapter in my life."
It's been a roller coaster summer for the Real Housewives of New York star, following allegations that Mario was having an affair with another woman. After the rumors surfaced, it appeared they had reconciled when Ramona shared a photo of them together on Twitter with the caption, "What doesn't break you makes you stronger."
Despite their troubles, Ramona was optimistic they could work things out, saying in April, "[We] feel very positive about [our] future together. All marriages hit bumps, some bigger than others."
The couple, who have been married for 25 years, have one daughter, Avery, who is enrolled in college.
On this year's RHONY reunion, Andy Cohen tried to get Ramona to talk about the state of her marriage. Watch below.
