Lamar Odom and Khloe Kardashian haven't had an easy time lately. Odom has allegedly been using serious hard drugs and possibly cheating on the reality starlet. Though she initially was focused on saving Odom more than for punishing him for his transgressions, it appears that she's finally had enough. Why?

Because, like all celebrities who want to send a subtle, passive aggressive message, Khloe Kardashian Odom has removed the "Odom" from her Instagram handle.

Don't think it's a big deal? Think back to what happened last week when Miley Cyrus and Liam Hemsworth first unfollowed one another's Twitter accounts. (Hint: It's a big deal.)

While at first there looked to be hope for the once-head over heels couple, sources close to the K Klan (no, the other one) say that a divorce is imminent, though Kardashian hasn't made a decision just yet.

An insider told Radar Online, "Khloe is steadfast that she won't decide whether she wants out of the marriage until she is done shooting the current season of the show. She has been through so much the last year with Lamar, and Khloe just doesn't want this to be played out in front of the cameras."

The source added, "It's a very sensitive situation, she is being a trooper and is being a total professional while shooting. Another reason why Khloe isn't making any decisions yet, she doesn't want this to loom over Lamar in the future, no matter what she decides to do."

As painful as it is, that sounds like true love to us. Unfortunately, it just may not be enough to save Odom nor their marriage because of his infidelity.

"She just can't trust Lamar. She could stand by Lamar if he had chosen to get help for his drug addiction, but the cheating is what she can't get over," the source lamented. "Lamar was unfaithful to her for a very, very long time. Not only did he betray the vows of their marriage, but placed her health in jeopardy because Lamar often had unprotected sex with multiple women."

Repeat after us: Yikes.

Still, all hope isn't necessarily lost: Kardashian rocked her giant engagement and wedding rings at the iHeartRadio Music Festival this weekend, where she hung out with fellow Lonely Hearts Club member Cyrus. Quotes the source, "Anything is possible. Khloe loves Lamar, and always will -- but the longer Lamar goes without getting help, the less likely the odds are that the marriage can be saved."
