Robert Jr. was once described by Mary as the “perfect child,” excelling academically and showing immense promise. However, his struggle with substance abuse emerged unexpectedly, shaking the family to its core. Mary’s candidness about this difficult chapter has resonated with many viewers, shedding light on the complexities of addiction and the importance of compassion and support.

A Mother’s Love and Struggle: Mary Cosby’s Journey

In a 2024 RHOSLC confessional, Mary revealed the shock and heartbreak she felt upon learning about Robert Jr.’s addiction. “Robert was, like, the perfect child. He was very good in school, he got straight As. All the way up until he graduated,” she shared. “When he set his mind to do something, he did it. He was, like, our prize. Very smart, very advanced. That’s the Robert I know. That’s the Robert I’m trying to reach.”

Despite her initial disbelief, Mary did not shy away from confronting the reality of her son’s struggles. She expressed feelings of self-blame, saying, “I feel like I let him down somewhere… I trusted him in my mind, thinking that’s where he would stop. I was clearly wrong. I missed the mark.” This honest admission highlights the emotional toll addiction takes not only on those affected but also on their loved ones.

Mary also emphasized the importance of support within the family, particularly from her husband, Robert Cosby Sr., who has personal experience with substance abuse. “He’s experienced drugs when he was younger, so he would be able to guide Robert better,” Mary explained. This partnership was vital in navigating the challenges they faced as a family.

Throughout 2024 and 2025, Mary shared updates on Robert Jr.’s progress, expressing pride in his commitment to recovery. “He did go to rehab, he stayed for a month [and] he completed it,” she revealed on Watch What Happens Live. “He did an excellent job, he came out [a new person].” She also noted that he was “steady” in his sobriety journey, taking it “day by day.”

Despite these hopeful moments, the battle was far from over. In January 2026, Mary disclosed that Robert Jr. had been incarcerated for violating a protective order, a setback that underscored the complexities of addiction recovery. Yet, she remained optimistic, telling reunion host Andy Cohen, “I’m happy. I’m in a good place. I’m not worried about him. I know he’s somewhere where he’s not using.”

Tragically, Robert Jr. passed away in February 2026 from a suspected overdose. Mary and her family released a heartfelt statement: “Our beloved son Robert Jr. has been called home to the Lord… Though our hearts ache, we take comfort in God’s promise and in knowing he is finally at peace.”
