Life isn't easy right now for Khloé Kardashian Odom.
The E! Star—whose husband Lamar Odom was recently charged with one count of DUI in the wake of his battle with substance abuse—is doing her best to stay strong and focus on own well-being after unsuccessful attempts to help her husband of nearly four years overcome his recent struggles.
"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."
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.
"It is what it is. She's trying to just live her life, even though it's very separate from the life he's living," the insider says.
Although the couple's troubled marriage has taken a backseat to Lamar's addiction, the source believes that ultimately, their romance will end in divorce.
"It's not at the point where she's ready to file divorce papers," the source reveals. "But she's pretty much given up trying to save the marriage."
An insider previously told E! News that "divorce seems imminent" for the pair after Lamar's less-than-24-hour stay in rehab, adding that Khloé is "heartbroken" over the pair's marital woes.
"They just want to support her and keep her spirits up," the source explains.
Khloé most recent Instagram featured a woman wearing a mask with the text, "She smiles to mask the pain in her heart. She laughs to conceal the tears in her eyes."
She is expected to travel to Las Vegas for the iHeartRadio Festival this week.
