luann de lesseps is head over heels in love with Thomas D'Agostino on “The Real Housewives of New York”. The two met while she was filming the previous season of the show and she was clearly excited when he popped the question. The two got engaged after dating a few months and within a few weeks, she was already planning her wedding, which took place on New Year's Eve 2016.

Just a few weeks prior to getting married, her “Real Housewives of New York” co-stars were concerned about her relationship. They had learned that he had supposedly kissed another woman and hooked up with others, clearly showing that he was not faithful to Luann.

But she was living in her happy bubble and she wanted evidence of his cheating if she was to change any of her wedding plans.

Could Thomas have cheated once again?

On “The Real Housewives of New York”, fans can clearly see how some of the girls are concerned about Luann's relationship with Thomas. They really want him to own up to his cheating and they want de Lesseps to leave him and find a man who isn't unfaithful to her.

But de Lesseps doesn't exactly believe what her co-stars are telling her. If she's going to leave him because of cheating, she wants evidence. She already knows that he cheated once, but she wants text messages and proof that he's actually stepping out on her.

"Also, if the girls had texts insinuating that Tom acted inappropriately, why didn’t they show them to me?" Luann de Lesseps reveals in her Bravo blog, adding, "It was logistically impossible for Tom to do these things!"

Would Luann believe people about his cheating without evidence?

While all of the ladies have plenty of things to say in regards to his supposed to cheating, Luann doesn't take it seriously.

As she points out, when would he have the time to be cheating on her? Ramona Singer has an answer for that.

She found out from one of her friends that Thomas has cheated on her while they were fighting. He may just have had a single fight with Luann, stepped up for a couple of hours, cheated on her and then going back with her. At least this is what her co-stars want her to believe.

While the theory may sound crazy, he could be doing this if he wanted to cheat and not get caught. It may be outrageous, but it isn't impossible
