‘Bachelorette’ Kaitlyn Bristowe’s Tearful Regret: ‘You Make One Mistake… Feel Like Worst Person in the World’

After Monday's much talked-about episode of “The Bachelorette,” Kaitlyn Bristowe confessed to being intimate with suitor Nick Viall on their first one-on-one date in Dublin, but the next day she had some serious regrets about the romance.

“I'm feeling guilt,” Kaitlyn explained to the cameras. “I don't necessarily feel guilty about the act, but for the relationships I have. I'm concerned Nick will say something to the guys, and I don't know how to deal with it and I don't know how to fix it.”

The morning after Bristowe broke down in tears in front of cameras. “You make one mistake and you feel like the worst person in the world.”

Contestant Nick Viall took to Twitter to defend Bristowe last night after the episode aired, writing, "There is a more to intimacy than just sex. Kaitlyn showed a lot of courage by admitting 2 having sex on national TV knowing that she will be unfairly judged by some.”

Bristowe said Tuesday morning on "Good Morning America," "I am a very in the moment person and I tried to just separate each relationship, and they all move at different paces, and that one definitely moved a little quicker than others and maybe the timing wasn't ideal on that one."

She continued, "I always wonder if I would have waited 10 days and it was the Fantasy Suite and I didn't talk about it, would I be getting the same response from people? Probably not. I don't know, I worried about jeopardizing other relationships."

Bristowe also fired back at critics on social media. “Just remember, when you judge me, you do not define yourself. Think about that before sending out negativity to anyone tonight.”
