Shawn Booth’s First Words on Kaitlyn Bristowe’s New Romance with Jason Tartick

"The Bachelorette" alum Kaitlyn Bristowe has moved on from Shawn Booth, but how does he feel?

After they ended their engagement, Bristowe is now dating “Bachelorette” alum Jason Tartick, who has been appearing on her social media lately.

Booth weighed in on the romance on Ben Higgins and Ashley Iaconetti's podcast “Almost Famous: In Depth,” saying, “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.”

Booth seems upset, emphasizing, “Not only were we engaged, but it's like, man, I lost my best friend, too.”

When asked the toughest part about the split, Shawn said, “It just feels like everything is just completely gone, like that Kaitlyn and Shawn [are] gone."

Booth noted that social media is making it hard for him to move on from the relationship. He explained, “Everything we've had, everything we've been through — we were this team and we got through a lot of stuff together, but then just like in an instant it's all gone, so it's just trying to move on from that and then stay positive about it and not let the outside noise take you down too much because living in a world where everything is on social media, you know it's nerve-wracking everytime I pick up my phone.”

“I haven't been on Twitter in months just 'cause I don't want to scroll the mentions and then going on Instagram, I do that for business purposes — obviously get caught with scrolling and that's always tough because, you know, you have a pit in your stomach,” Booth continued.

As for her new relationship, Shawn admitted, “Just kind of makes me question everything that we've had, so I think that's one of the major questions that runs through my mind — just trying to understand that, which I think is tough to understand, but so I ask myself those questions."

Despite being hurt, Shawn still had some positive things to say about his ex-fiancée. He said, “There's a part of me that is, I do care about her, so I am happy that she doesn't have to really, I guess, deal with maybe all the pain and the heartbreak because it seems like she's moved on and she's happy, so that's gonna make me a little more comfortable knowing that, that she's not at home at her empty house, so I look at it from that point of view and then I also think that it's helping me to move on because it does hurt that much seeing everything, it does upset me, and it does make me a little angry, but it also helps me to move on knowing that maybe we weren't right for each other and that I will find somebody down the road that will also make me happy."
