When Bachelor finalist Courtney Robertson and Arie Luyendyk Jr. were first spotted kissing at a restaurant in Phoenix on Oct. 11, Courtney insisted it was a onetime hookup. But now Courtney reveals to Life & Style that she and the latest Bachelorette runner-up have become something more.

“Yes, I’m dating Arie,” the model tells Life & Style. “We’re enjoying our time together.”

That, she says, is a welcome change from her relationship with her ex-fiancé, Ben Flajnik, “I was miserable with Ben; he treated me so badly,” Courtney says.  She had planned to move to San Francisco to be with The Bachelor star, “but he was all like, ‘I just turned 30, and I’m not ready,’” says Courtney.

It’s been only a month since her engagement to Ben ended, but Courtney insists she never planned to move on so quickly. “I didn’t want to jump from one public relationship to another,” she admits, “but Arie and I get along, and I’m not going to let that get away.”

Courtney tells Life & Style that she and Arie, a race-car driver, have been secretly spending time together, and he stayed at her place in LA in November.

“Arie makes me laugh so hard, and he’s adorable, so I’m going with it,” Courtney raves, noting they’re not dating exclusively yet, but she’s not sure she could find a better guy!
