Last month, Kim Richards celebrated 60 days of sobriety.
Kim's battle with addiction has been anything but easy, and her family fears that an upcoming challenge may derail months of progress for the former reality star.
Kim's ex-husband Monty Brinson is suffering from stage four lung cancer, and doctors have reportedly informed him that the time has come to make his final arrangements.
Obviously, that's sad news under any circumstances, but Monty's passing will be made all the more tragic if it triggers a relapse for Kim.
“Kim has been by Monty’s side since he was diagnosed and when he passes she is going to be devastated,” a source close to the situation tells Radar Online.
“Everyone is worried that his death will compromise her sobriety, since she is just so newly sober.”
According to social media updates from Brinson's other ex-wife, Terri Doss, the supermarket heir is "not of sound mind," having recently suffered a stroke that has "affected his decision making" and altered his personality.
Kim moved back in with Brinson last summer, but sources say their relationship remained purely platonic.
It's not known if the ex-couple is currently still living together, but insiders say Kim still considers Monty the love of her life.
