The 30-year-old issued a public apology to Kardashian earlier this month after it was established he fathered a child with Maralee Nichols while he was seemingly still with the reality star last year.
Though Kardashian has since shared cryptic quotes hinting at how she's doing during this time on her social media, she has not directly commented on the scandal.
An insider told Page Six the Good American cofounder decided against publicly responding to Thompson's apology. However, the source revealed she reached out to her baby daddy privately to let him know she appreciated the sentiment.
"She is taking the high road, and while she will never, ever get back with him, Khloé really wants Tristan to be a good father to [their daughter] True, and for him to be a big part of their daughter’s life," the source reportedly explained. "She’s a great mom and she wants her daughter to have a good relationship with her dad … So for that reason, Khloé is not going to fight with Tristan or block him from the family."
Thompson's third baby mama drama began in December when it emerged that Nichols was suing the Sacramento Kings player for child support after they hooked up in March. The NBA player and Kardashian were believed to have still been together at the time before they called it quits for good over the summer.
After it was determined that he was the father following the December birth of his son, Thompson issued a statement taking responsibility for his actions. "I sincerely apologize to everyone I've hurt or disappointed throughout this ordeal both publicly and privately," the father-of-three wrote on his Instagram Story earlier this month.
Thompson also publicly acknowledged Kardashian doesn't deserve all he's put her through. "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 shares 4-year-old son Prince with ex Jordan Craig.
