Audrina Patridge called it quits with BMX-riding Aussie hottie Corey Bohan on TV in the past – but unlike during her Hills days when the duo dated casually, their breakup on her upcoming VH1 reality show, Audrina, was way more emotional.

"It's something that was an ongoing thing that I talk about in the show," Patridge, 25, told PEOPLE Wednesday night during the premiere party for her new series at The Library lounge, inside Hollywood's Redbury Hotel. "It was a long time coming. Enough is enough. You get to a point where you're just ready to move on and you can't take it anymore."

Patridge doesn't give away too much – but she says the relationship wasn't officially over the very end of shooting.

"You've just got to move on, and sometimes you've got to think about yourself instead of trying to people please," she said. "On the show you'll see what led up to our breakup. There's a reason for everything."

Patridge also says she took new risks while filming this show, which debuts April 17, but she has no regrets.

"I honestly did not say 'no' to anything they wanted to shoot," she said. "They caught everything on camera, so it was very organic."

As for her personal life now, the reality starlet has apparently taken her own advice: She seems to have moved on to a new relationship and was spotted holding hands with polo player Nic Roldan in Mexico recently.
