The "Selling Sunset" star took to her Instagram Story on Friday to post a screenshot from a report saying, "Keo is heartbroken. He enjoyed his time with Chrishell and was 100 percent in it... He's had a tough time with his mom's passing, but he really wanted to make his relationship with Chrishell last."
"I gathered all the facts before I posted," wrote Chrishell. "Don't worry. I know exactly where it came from."
And less than an hour later, she posted another suggestion from a fan who wrote, "I think you're too mature for all this. It's best to ignore it, this kind of comes off childish."
"Yes I am aware," Chrishell replied. "If I end up alone with cats - it was worth it. But I am also human and not a robot. When you are the ass in the breakup & then the other person tries to let you save face and take the high road publicly... probably best not to poke a bear holding receipts. I will try to be a better person tomorrow."
She added, "Today wasn't the day."
On Friday, it was reported the pair called it quits after three months of dating. They had met on season 29 of "Dancing with the Stars" as Chrishell was a contestant and Keo a dance pro.
The news of the split comes as Chrishell's divorce from Justin Hartley was finalized on Monday.
