The Bachelor’s Jason Mesnick and Molly Malaney opened up about their controversial relationship in a chat with talk show host Ellen Degeneres on Friday.

On The Bachelor finale on Monday, Jason stunned fans by announcing to his fiancee Melissa Rycroft that he was leaving her for Molly, the show’s dumped runner-up. The decision to break up with Melissa on national television has turned the single dad into one of the most disliked men in America.

(And rightfully so, what a creep!)

“I completely regret doing that,” Jason told Ellen on today’s show. “I regretted it every single day since that happened and I will regret probably every day for the rest of my life. The producers obviously really wanted me to do it on the show, but I take full responsibility for my actions.”
