"It's not at the point where she's ready to file divorce papers, but she's pretty much given up trying to save the marriage," a source told E! News."
"She is still obviously very upset, but life is starting to move on for her and for the rest of the family. No more interventions, no more trying to save him."
In light of all Odom's recent problems that have put strain on their marriage, Kardashian reportedly told her husband to clean up his act or he'd lose her forever.
"Khloe gave Lamar an ultimatum: If he didn't get help, she'd end the marriage. So far, he's ignoring her," the source added. "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."
Odom, a 33-year-old NBA basketball player, and the "heartbroken" Kardashian are reportedly not trying to work things out as of recently. The Keeping Up with the Kardashians star's family is simply there to "support her and keep her spirits up."
A friend of Kardashian's also told Us Weekly a separation is imminent for the pair, who have been married for four years and have their anniversary coming up on September 27.
"She'll be the one who ends things, and it will be soon," the friend told Us.
Odom has denied all recent allegations regarding his drug use and deteriorating marriage. The arraignment for his DUI charge is unfortunately scheduled on the same day as his wedding anniversary in Van Nuys, CA.
