After years of heartache, Khloé Kardashian filed for divorce from her estranged husband Lamar Odom and was ready to move on – until he was fighting for his life after overdosing in a brothel.

A sneak peek at Sunday’s episode of Keeping Up with the Kardashians shows Kim Kardashian West discusses the status of her sister’s relationship with the former basketball player.

“I feel like you finally are done,” says Kardashian West, 35. “You’re was closer to being over it.”

“Because you mistake my kindness for me going back with someone,” Kardashian, 31. “You don’t marry someone and then you could cut them of your life that easily. I care about Lamar, so I want the best for him. I want the best for his wellbeing.”

Of course, the scene was shot before Odom, 36, was found unconscious and Kardashian rushed to his side, asking a judge to dismiss their nearly finalized divorce petition.

Though the reality star remains his caretaker, she is now dating Houston Rockets shooting guard James Harden and told PEOPLE in October that she’s not getting back with Odom.

“I want to be his support system,” she said. “Tragedy does make you reassess a lot of things, but when it comes to our relationship, it’s the same, except I’m here supporting him fully.”
