Kardashian reportedly thinks a divorce is "inevitable," according to sources, but she fears Odom would overdose on drugs or intentionally commit suicide if she ends their marriage.
The reality TV star has currently revolved her life around her troubled husband and is allegedly neglecting to take care of herself first.
Us Weekly reported last week Kardashian had told Odom, an alleged crack cocaine addict, she's filing the divorce papers soon.
A possibly telling sign Kardashian and Odom are headed for a split occurred on September 27, the date of their four-year wedding anniversary. Kardashian tweeted a photo of a gift she had received from her girlfriends -- a rough-cut glass heart that read, "Khloe, Love you 4 ever, Malika & Khadijah" -- rather than something from her husband.
