Former The Bachelor star Andrew Firestone is not buying Jason Mesnick's sob story after dumping fiancee Melissa Rycroft for Molly Malaney.

"If he didn’t have his mind made up, don’t do anything," Firestone said.

"Don’t feel that you are so pressured into having to propose or make a decision. There’s no reason that you have to do anything, especially if you’re so torn that you’re crying like a little girl on that balcony."

"He was faking it so much that he was crying uncontrollably, then [showed] uncontrollable elation, so he was either lying to one or the other, convincingly."

Andrew Firestone proposed to Jen Schefft on his 2003 finale, and although the couple later split, he doesn't regret his decision at the time.

"It wasn’t like, 'Eh, you know what, flip a coin.'"

Firestone, who said he traded a few emails about Mesnick's behavior with former Bachelorette contestant Trista Sutter, agrees that ending the engagement on the show was inappropriate.

"Don’t drag the poor girl on national TV," he tells Us Weekly. "I think the main thing, you’ve got to act like a gentleman."

The 33-year-old, who is now expecting his first child with wife Ivana Bozilovic, doesn't fall for what he calls Mesnick's "aw shucks, poor me" attitude.

"I think it’s a front - him crying. I think it’s so much more calculated," Firestone says. "But he always tried to be the guy next door. I don’t even know what his motivation was, whether it’s being on TV or whatever it is."

Instead, Firestone says he believes that The Bachelor star "was acting like an ass" during the finale and After the Rose special.

"I thought it was super shady that Jason has one girl on and then he did the squirmy, puppy dog kind of thing," Firestone says.

"[Melissa Rycroft] goes walking off and then the other girl comes on, and he’s sheepish and making out with her. Come on."

"He keeps saying, 'Oh, nobody knows what it’s like,' but ... nobody would put themselves in those shoes. Those are shoes that nobody wants to wear. He can keep saying, 'Oh, you’re not in my shoes.' Well there’s a reason for that, because I choose not to put those shoes on."

Still, the former rose-giver wishes him the best of luck.

"I hope that Jason and that other girl are truly happy and all that," he said. "This might sound malicious but what a stupid thing to do."

"It’s kind of a little depressing. This guy’s a father, and you’d think he’d be kind of a stand-up guy. He does the whole thing, I certainly would never coach my son to be anything less than a gentleman. Just act like a gentleman!"
