Ramona Singer might be trying to save her marriage, but it looks like her husband Mario is trying to save her and her alcoholic ways. A new report suggests that the reality television couple is at odds once again as Ramona is having a difficult time controlling her drinking while the two are trying to save their marriage while on vacation in St. Barth's this week.

Ramona Singer's Husband Still Cheating On Her With His Mistress?  

According to a source, the couple was overhead fighting poolside while on their vacation because Mario had enough of Ramona's out of control drinking during their stay.

"Ramona and Mario were at the pool on Sunday afternoon, and he was very upset that she had over indulged at dinner Saturday night," a source told Radar Online Monday. "Specifically, according to Mario, Ramona had too much to drink."

Why Did Ramona Singer Send Kasey Dexter A Threatening Letter?  

The source went on to say further that Ramona must have gotten her husband's message, because by the next day, she swapped her glass of wine for non-alcoholic beverages instead.

"Ramona didn't say much in response to Mario, but did ask him to keep his voice down. She was only drinking water at the pool on Sunday," the source added.

Meanwhile, it also seems as though the Real Housewives of New York star is staying mum when it comes to rumors surrounding her husband's alleged mistress, Kasey Dexter.

Rumor has it that the blonde beauty "shuts down" conversations about her husband's affair with her friends, leading to the speculation that she is "in denial" about the entire issue. Her husband Mario was caught cheating on her with his mistress Kasey Dexter during a trip to the Hamptons earlier this year.

"Ramona NEVER talks about Mario or the mistress, she absolutely shuts down cheating talk," a source close to her told Radar Online. "Ramona refuses to acknowledge that there is a problem. She is burying her head in the sand and refuses to talk about what had happened."
