Lamar briefly entered rehab earlier this month, but checked out after less than one day.
Prior to his short stint, an insider told E! News the 29-year-old beauty and her family had been urging Odom to seek treatment following his DUI arrest.
“Khloé gave Lamar an ultimatum: If he didn’t get help, she’d end the marriage,” the source explained. “So far, he’s ignoring her.”
While Khloé’s done everything in her power to help her hubby, the source says she’s now come to terms with the fact that she may not be able to save Lamar.
“She is still obviously very upset, but life it starting to move on for her and for the rest of the family,” a source tells E! News. “No more interventions, no more trying to save him.”
