Looks like Ramona Singer is officially pulling the plug on her marriage – again.
“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,” she Tweeted Thursday.
Singer, 57, initially filed for divorce in January after the reality star discovered her husband of 22 years trysting with his girlfriend at their Hamptons home. A tabloid report indicates Singer discovered her husband with the girlfriend again just last week.
The split comes four months after the couple seemingly reconciled. In April, she told PEOPLE they “feel very positive about their future together.” She also Tweeted a happy photo of the duo, which she captioned “What doesn’t kill you makes you stronger.”
However, trouble seemed evident this week when Singer got into a testy exchange with Andy Cohen, who was hosting The Real Housewives of New York City reunion specials.
“Everyone in my family is doing well,” Singer said sharply, declining to comment further because of her daughter. “Mario and I are together … Let’s go to someone else. Thanks, Andy.”
In January, a source told PEOPLE Singer was devastated after catching her husband and his girlfriend, said to be in her early 20s, together in the Hamptons.
“Ramona did not want this divorce,” the source said. “Ramona loves her life. She loves Mario. She loves the image of her being one of the only ones who was married for that long. She loves to throw that in everyone’s face, like Luann, to say how perfect her life was. But everyone knew Mario was a cheater … She looked the other way.”
