“Story time on how my ex-boyfriend cheated on me with his sister,” Katelyn began in the clip. She explained that they had been together for about a year and appeared to everyone else as the kind of couple that would last forever.
But there was one constant problem: his sister. “She hated me for literally no reason,” Katelyn stated, adding that this was strange since his whole family liked her.
The sister talked badly about her around the entire school, but when Katelyn confronted her boyfriend about it, he brushed it off.

“He would tell me that I’m insane and I need to get over it,” she recalled. Over time, the red flags grew harder to ignore. “He was always, like, kind of weird with his sister,” Katelyn stated.
“He’d always make really weird remarks about how she looked and her body looked. It low-key kind of brushed me off, like, really weird. Like, that’s his sister.”
Still, she tried to stay rational. “Because who would think that you’re banging your little sister? Not me.”

The breaking point came one night after a fight. Katelyn had plans to hang out with a friend, but her boyfriend didn’t approve. Despite his objections, she went anyway.
Later, she noticed something strange. His phone’s location had been stuck at a nearby park for half an hour.
“His location is set at the park for like 30 minutes,” she recalled. “And I’m like, okay, whatever. But he’s acting really weird.”

Trusting her gut, she and her friend decided to check it out. “Me and my friend walked to the park without him knowing. And I turned off my location.”
As they got closer, her worst suspicions were confirmed. “As we get closer to the park, I hear talking, and it’s a girl,” she said. “As I get close enough to see them, I see his sister and him. I see them doing something crazy that you should never do with your sister.”
Katelyn stated that she could not help but yell out, causing the pair to immediately freeze and panic. “They were shaking,” she recalled. “I was just so disgusted. I was like, 'That’s your sister!'”

Her boyfriend allegedly tried to explain, stammering, “It’s not what you think, I promise. Like, I can explain.” But Katelyn stated that she refused to hear another word.
“I was like, oh, hell, we’re leaving right now, because what does one do in that situation when you see your boyfriend doing a squirrel dance on his sister?”
The next day, Katelyn stated that the tables were turned when her ex started spreading rumors about her instead.
“He started telling people that I had cheated on him,” she said. “He didn’t tell people that he did the renegade on his sister. Because that’s crazy.”
Katelyn ultimately decided to be the bigger person, because she did not out her ex’s rather curious relationship preferences.
