Shawn Booth's Reaction to Kaitlyn Bristowe Dating Jason Tartick Is So Shady. It's been three months since Kaitlyn Bristowe and Shawn Booth announced they were the latest Bachelor Nation couple to call it quits, and it's been two weeks since Kaitlyn and former Bachelorette contestant Jason Tartick went public with their relationship and deemed it "life changing." Now, Shawn is so over Kait-son. Some background: Shawn isn't just over Kaitlyn's new relationship like any ol' ex would be. No, he's totally over it because she and Jason post about their newfound love on social media a bunch (as they can/should!), and she made it known to her podcast audience that Jason is basically the perfect man. Shawn recently told his fellow Bach nation buds Ben Higgins and Ashley Iaconetti that sh*t stings. He said, "I think just with her moving on so quick, I just have a tough time understanding why she would be putting this out everywhere or blasting it all over the place knowing that it could hurt." While it seems Kaitlyn and Jason's relationship is just weeks old, Shawn said they actually started dating back in November...not long after they called off their engagement. Awk. "Not only were we engaged, but it's like, man, I lost my best friend, too," he added. "It just feels like everything is just completely gone, like that Kaitlyn and Shawn gone." Shawn also said that while he's happy she's moved on, it does still hurt. He explained: That's right, dude. Always look at the bright side!
