And although the 31-year-old insisted that he was "not done" with his treatment after staying just a week, and that he planned on returning to the lush facility, a source close to the family tells RadarOnline.com exclusively that he's changed his mind.
"Scott told Kourtney and the rest of the Kardashians that he does not want to go back to rehab," the insider says. "He thinks that he has his drinking under control. Scott actually says he has it under wraps, but no one is buying his bullsh*t anymore!"
Disick's issues became apparent when he was hospitalized for alcohol poisoning in June 2014. He has since struggled to maintain sobriety and has had several relapses, which have been documented on KUWTK and Kourtney & Khloe Take The Hamptons.
This past weekend, after Disick chose to party in Las Vegas rather than be there to support Bruce Jenner and the family, "Scott really showed Kourtney where his priorities are. And it's not with her," says the source.
In fact, he recently announced several upcoming club appearances in Sin City.
"Kourtney is just so beyond it that she almost doesn't even care what he does anymore," the insider tells Radar.
