Real Housewife Ramona Singer took to Twitter on Thursday, Aug. 7, to announce plans to end her more than 20-year marriage to husband Mario Singer.

Just one day after In Touch published a photo of Singer's husband out dining with fitness instructor Kasey Dexter, with whom he allegedly had an affair earlier this year, the "Real Housewives of New York City" star shared the following tweet with fans:

I have decided to move on with my life without Mario. I tried my best to make my marriage work. I am excited for the new chapter in my life.

Rumors of separation have circled the couple since Ramona discovered Mario's relationship with Dexter earlier this year, but the husband and wife appeared to have been trying to work things out this past March, when Ramona made a statement on Bethenny Frankel's show that emphasized their love for each other.

"Really, right now, I don't know where this is going," she said. "I have myself, I have my friends. I know my husband loves me, he knows I love him, and we'll see what will happen, you know?," she continued. "Nothing is set in stone, life is an evolution. And again, ladies and gentlemen, as long as you feel good about yourself, you can handle anything."

The reality TV star has apparently since changed her plans, and has received an outpouring of support from fans since announcing her intentions earlier this afternoon.
