To say the last six weeks have been difficult for Khloé Kardashian would be an understatement.
Since the news broke of husband Lamar Odom’s drug addiction and alleged infidelities, the E! personality has been toiling over how to move forward.
Now, sources close to Kardashian, 29 – who has been living separately from her husband for weeks – tell PEOPLE that she is finally accepting her marriage may be over.
“She just doesn’t know if she can work this out,” says a Kardashian pal.
Another source in Kardashian’s inner circle adds, “It doesn’t seem like a reconciliation is any closer to happening. It’s like the situation is just too far gone at this point for a split to be anything but unavoidable.”
Regardless, friends say the reality star is not taking lightly any decisions about her future with Odom, 33. “Two years ago, Khloé thought they’d be married with two kids,” says the pal. “There’s still a lot of uncertainty.”
And maybe even a flicker of hope. Although Kardashian has removed the surname “Odom” from her social networking profiles, on Wednesday she Tweeted: Promise me u’ll always remember: u’re braver than u believe. I am brave because of u. The love u gave made me brave. All we need is love#KKO.
The hashtag “KKO”? Those are her married initials.
