"We were kind of struggling for the last little while... I just wasn't feeling loved for over the last year," Kaitlyn, 33, said of her relationship with Shawn prior to calling it quits in November 2018.
"It really just started weighing on me. I just felt very alone in the relationship and I felt like I had a best friend but I didn't feel like I had a partner. We just started growing apart."
Kaitlyn and the 31-year-old Boothcamp Gym owner apparently waited to tell the world their engagement had ended because they "didn't want to face what was coming with it."
"This breakup just felt very different to me, and difficult in many more ways, just because it was, obviously, so public," Kaitlyn explained, adding that she felt she had to put on an "act" for social media followers that her life with Shawn was perfect.
Kaitlyn, however, insisted she "knew she would be okay" because splitting from Shawn after three years together was simply "the right decision."
Kaitlyn revealed on the podcast she realized during a Summer 2018 trip to her native Canada her relationship with Shawn wasn't going to work out because he didn't seem to be "on the same page" as her.
Kaitlyn and Shawn got engaged during the finale of The Bachelorette's eleventh season back in 2015.
When they finally announced their devastating decision to part ways, the couple released a joint media statement saying they'd be "committed to remaining friends" and supporting each other but their lives had led them "in different directions."
