Melissa Rycroft on Ellen DeGeneres Show

On Today's Ellen DeGeneres Show, Melissa Rycroft opens up for the first time  about being dumped by her Bachelor fiance Jason Mesnick, on national TV and how hurt she was when she found out he was dating runner-up Molly Malaney.
 

"They both did betray me" Rycroft says, even though d-bag Mesnick initially denied he was dating Malaney.
 

"Being a girl, you get that feeling," she says. "Anybody that's been cheated on, you know. And being a woman, I got that feeling, because he just backed away from me, and I knew he had contacted her."

"Once we got back, we both kind of sat in the real world, and we were talking about how [our relationship] was different," she says. "He kind of gave up, and I couldn't understand why at the time. Now I do - because I think there was someone else involved."
 

"And that is where my feelings of betrayal came in," she goes on. "I knew on the night After the Final Rose [aired], I wasn't getting dumped. We had already ended the relationship and that was mutual."
 

"I repeatedly asked him, 'Is Molly involved in anything?' And when they moved up the taping of After the Final Rose, I was going, 'Why did we move the taping up? What's going on?'"
 

"I asked Jason, 'Am I going to be blind-sided by anything? Is there anything you want to tell me?' And he said, 'No, gosh no.' And the second I went out on that stage, he goes, 'P.S. it is Molly.' And I went, 'Bastard!'"
 

Rycroft says she is moving on and is dating a new guy named Ty. The episode airs Thursday, March 5.
