Who is Kat's boyfriend on Survivor?

I'm curious to know, could you please clarify who Kat's boyfriend is on the popular reality show Survivor? As a fan of the series, I'm always intrigued by the personal lives and relationships of the contestants, and I'm wondering if there's been any mention of a significant other in Kat's storyline. If so, could you provide some details about their involvement, if any, in the show and their impact on Kat's journey? I'm eager to hear more about this aspect of her Survivor experience.
