Khloe says she was reluctant to continue seeing Tristan when he confessed to a pregnant ex ... but believed him when he and his people told her he and her ex were done.
"He pleaded with me that the relationship was over before we met," Khloe says. She claims he showed her evidence.
"This is MY TRUTH," Khloe says, and insists she had no idea the two were still together and that she was "so completely and utterly sorry" but pins the blame on those who lied to her.
"I pray my truth is in fact that," she wrote. "Lord knows I pray but now, I really don't know what to believe."
