Ramona Singer's Husband Mario Dumps Mistress Kasey Dexter

Ramona Singer already filed for divorce from husband Mario Singer, but he may not be ready to let the marriage go. In a new report, it has been revealed that Mario, in what may have been a last ditch effort to save his marriage, has kicked his younger woman, socialite Kasey Dexter, to the curb.

“Mario had been seeing Kasey behind Ramona’s back for eight months and was giving her the usual line that he’d marry her after he left his wife,” an insider revealed to Star Magazine in the issue out Wednesday. “But after the affair blew up in public, he blindsided Kasey by cutting off all communication with her.”

In addition to sleeping with Kasey, Mario also reportedly bought her an apartment and had been taking her to all of Ramona's favorite places in the Hamptons. They went on several dinner dates and often took their trysts to hotels in town, as well.

According to sources, Kasey is devastated about the breakup. “She really does love Mario — but now he won’t give her the time of day,” the insider said.

Kasey has even taken to Facebook where she has hinted at a breakup a couple of times. Last week, Kasey told her friends and followers that she needed to “blow off some steam!” More recently, she wrote a message to a friend, which read, “It’s been a sad couple of days."

Despite this affair coming to a possible end, Ramona is moving forward with the divorce. Although it has been what she calls "the most difficult time in my life," she has received tons of support from her fans, friends and family members.
