Mary Cosby's Son Robert Jr.'s Ups and Downs on 'RHOSLC' Before Death at 23 "I immediately started blaming myself, because I thought, 'You can't judge him and his life and his choices,'" she told Us in 2025. "I don't believe in judging people. I'm just not a judger. I don't like judging people, and I don't like to do it. ... If he's opening up enough to tell me something this crucial, then why would I judge? I have no choice but to sit there and receive it and accept it and hope that I can help him."

I'm not worried about him," Mary shared during the Bravo show's season 6 reunion in January when asked about Robert Jr.'s arrest. "I know he's somewhere where he's not using.
