Ramona Singer says "Things have come to a really big head" for Luann de Lesseps before returning to rehab

Luann de Lesseps was struck with moments difficult, as we have seen this season of The Real Housewives of New York . But after his divorce from Tom D 'Agostino, his arrest in Palm Beach, Florida, and his 21-day stay in an alcohol treatment center, Luann seemed to be back to his former fabulous life.

However, when the news announced last week that Luann had returned to rehab, it appeared that she still has work to do on the road to recovery. Bethenny Frankel, whom Luann authorized to speak on his behalf, confirmed Luann's return to detoxification at PEOPLE . "The recent extra family stress has been a catalyst for taking a break," she said.

Ramona Singer also shared that she thought "things have really gotten bigger" for Luann recently. "I think it pushed her to the edge of the abyss, and when you're pushed back, you go back to the demons, and her demon was the abuse of alcohol," Ramona tells The Daily Dish at the registration of RHONY ] Season 10 meeting. "So it's sad."

Luann did not appear at the registration of this season's meeting. When asked if she thought the ladies would be of great support when she was talking about Luann at the shoot, Ramona said, "Well, we have a reunion to make, and I think everything the world must own. Nobody is perfect. I mean, we're going to feel bad for her, but you know what, she must always behave. "

In addition to Bethenny, Andy Cohen also sent his love and support to Luann during this difficult time, with Dorinda Medley and Tinsley Mortimer expressing their sadness that Luann missed this season's reunion at 39 interviews with The Daily Dish at the time of registration
