Courtney Robertson has opened up about her relationship with former The Bachelor star Ben Flajnik -- and her comments are not very positive.

"I was miserable with Ben; he treated me so badly," Robertson told Life & Style.

Robertson, a 28-year-old model from Santa Monica, CA, got engaged to Flajnik, a 29-year-old winemaker from Sonoma, CA, when he selected and proposed to her during The Bachelor's sixteenth-season final Rose Ceremony, which was filmed in November 2011 and aired in March. However, the couple called it quits in October after only 10 months of dating. 

In their split announcement, Robertson and Flajnik -- who had maintained a long-distance relationship the last ten months -- stated they had "grown apart" due to "distance, time apart, and our need to focus on our respective careers."

According to Robertson, she had wanted to move to the San Francisco area to live with Flajnik, however he had been against the idea.

"He was all like, 'I just turned 30, and I'm not ready,'" she told Life & Style.

In addition, Robertson also confirmed she is dating The Bachelorette runner-up Arie Luyendyk Jr. -- whom she was spotted making out with as they shared an intimate dinner at a restaurant only days after her split from Flajnik.

"Yes, I'm dating Arie," she told Life & Style. "We're enjoying our time together."

"I didn't want to jump from one public relationship to another, but Arie and I get along, and I'm not going to let that get away," she said, adding that while they are not dating exclusively yet, he recently stated at her place in Los Angeles.

"Arie makes me laugh so hard, and he's adorable, so I'm going with it."
