Khloe Kardashian feels "crushed" after Tristan Thompson confessed to fathering a child with another woman.
The 30-year-old basketball player - who has True, 3, with the reality star - was recently revealed to have fathered a child with Maralee Nichols, and Kardashian still feels "unsettled" by the situation.
A source explained: "Khloe is really hurt and saddened by Tristan's actions and his public apology isn't helping. This has been a tough pill for her to swallow and she does feel unsettled and pretty crushed."
Kardashian and Thompson have had an on/off relationship since 2016.
The "Keeping Up With the Kardashians" star was looking to move in with Thompson, before it was revealed he had fathered a child with Nichols.
The insider told "Entertainment Tonight": "Khloe and Tristan were in a good place before the news about Maralee being pregnant came out and had plans to move in together.
"Tristan has since pulled out of escrow on his house in Encino, California, that he was in the process of selling, and is no longer moving in with Khloe."
Thompson previously apologised to Kardashian, after a paternity test revealed he fathered a child with Nichols.
The basketball player admitted Kardashian doesn't deserve the "heartache and humiliation" he has caused her.
He wrote on his Instagram Stories: "Today, paternity test results reveal that I fathered a child with Maralee Nichols. I take full responsibility for my actions. Now that paternity has been established I look forward to amicably raising our son.
"I sincerely apologize [sic] to everyone I've hurt or disappointed throughout this ordeal both publicly and privately.
"Khloe, you don't deserve this. You don't deserve the heartache and humiliation I have caused you. You don't deserve the way I have treated you over the years."
Thompson also insisted he has the "utmost respect and love" for Kardashian.
The sports star said: "My actions certainly have not lined up with the way I view you. I have the utmost respect and love for you. Regardless of what you may think. Again, I am so incredibly sorry."
