Khloé Kardashian has reflected on the process of learning to "unlove" her ex-husband Lamar Odom.

The reality TV star and basketball player wed in September 2009, just one month after meeting at an event, but split in 2013.

However, Kardashian halted divorce proceedings after Lamar was hospitalised for an overdose in October 2015, with the union finally dissolved in 2016.

Amid the season six premiere of “The Kardashians” on Thursday, the entrepreneur was filmed reuniting with the former sportsman for the first time in nine years, so that she could close that "chapter" of her life and return some of his belongings to him.

Recalling how she had to "break contact" with Odom after she cared for him for several months after the health crisis, Kardashian described how she was upset to learn that he was "repeating some of the same behaviours that I just couldn't stand for".

"I was very upset. I said to him, 'I'm going to Vegas. You need to be out by Monday. That's it, I'm done,'" she recounted of the time she kicked Odom out of the Calabasas house she was renting for him.

"And I haven't seen Lamar since that day."

After organising to meet Odom at her friend Malika Haqq's home, the reality TV star admitted her ex-husband appeared "nervous" and "scared".

"I have dealt with so much trauma in this relationship for years and this was such the love of my life that to learn how to unlove someone - to have to go through all that - it's almost like a death," the 40-year-old continued, adding that the moment felt "so familiar and so uncharted, all at the same time".

At the end of the episode, she was seen speaking with Odom, who joked, "My wife is the s**t."

"OK," the Good American founder quipped, before adding: "Calm down."

After parting ways with the 45-year-old, Kardashian moved on with NBA star Tristan Thompson, with whom she shares two children.

The TV personality is currently single.
