It looks as though Ramona Singer's marriage to her husband Mario has definitely seen better days. Rumor has it that the couple went on a "disastrous trip" to St. Barth's this past week to save their marriage but unfortunately things just went from bad to worse for the reality television stars.

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

According to a new report, the Real Housewives of New York couple looked like they were uninterested in each other and that Ramona's drinking and Mario's flirtations with other women has ruined their trip. An eyewitness who spotted them at a gas station says the married couple looked bored with each other as Mario shamelessly flirted with women on the island with his wife nearby.

"I saw him smiling at another woman at the gas station while he was pumping gas and then checking her out and smiling in the rear view mirror as they drove away," a source tells Radar Online. "However, he never turned toward Ramona, and she never even made any acknowledgements that he was even in the car with her. Just head down, reading her magazine."

Why Did Ramona Singer Send Kasey Dexter A Threatening Letter?  

In addition, it seems as though Ramona's drinking might be the root of their problem. Mario is said to be fed up with her constant alcohol abuse and that might also be the reason why he allegedly cheated on her earlier this year with his mistress, socialite Kasey Dexter.

"Mario says Ramona becomes a different person when she drinks and it's not a very nice person," the insider reveals. "He also revealed that all of the fights they have as a couple involve her use of alcohol, and he believes that he wouldn't have strayed if Ramona didn't have a problem."

Ramona and Mario have been married for over 20 years.
