Real Housewives of New York star LuAnn de Lesseps swears she never cheated on boyfriend Jacques Azoulay with Johnny Depp lookalike Tomas, but her hangout with the hunky Frenchman in St. Barts last year might have ultimately led to the demise of her relationship.

The Countess recently split from Jacques, her boyfriend of four years, and according to a new report from RadarOnline.com, trust issues were the main reason for the break up.

At the root of those issues was an incident that occurred last year on vacation in St. Barts in which LuAnn brought Tomas, whom she met at a club on a night out, back to the house she was staying at but told the other Housewives she was simply hanging out with a big group of her “Italian friends.”

“Jacques wanted to believe LuAnn and for a while their relationship appeared to be back on track,” a source told the website. “Then, the Countess began to pressure him for a marriage proposal and that is when the trust issues came up again. Jacques just couldn’t trust her and he decided to end the relationship.”

While LuAnn always denied cheating, she did address the incident last year on her Bravo blog. “Character counts and honesty matters. I’m sorry I concocted a story about my ‘Italian friends’ coming back to the house,” she wrote. “I admit that my problem is the cover-up not the crime. I can assure you once again that nothing happened with Tomas.”

Whatever the reason for LuAnn’s break up with Jacques, the housewife is reportedly struggling to come to terms with her newly single status.

“She really thought she was going to spend the rest of her life with him,” a source close to LuAnn told Radar. “Jacques treated her so well. She is very lost right now.”
