"I don't think he knows what he wants," Caroline toldPeople. "I don't think he's ready for anything."
Caroline, a 26-year-old Florida realtor, called Arie out on Sunday night's The Bachelor: The Women Tell All for decisions he had made at the end of Season 22 regarding his relationships with the Final 2 bachelorettes, Becca Kufrin and Lauren Burnham.
"This whole time you've said that you're here because you're trying to find a wife. I know what you did, and I don't know how you could do that," Caroline told Arie on the Tell All, as he appeared stone-faced and dumbfounded. "I just really don't understand."
Caroline has said that Arie hurt one of her best friends, who was left devastated and broken by the 36-year-old pro racing driver. Caroline therefore felt the need to put Arie in his place.
"I definitely had some things to say to Arie. I needed to say what I said. When somebody burns somebody you love, you want to have that moment where you get the last word in," Caroline explained.
"It was nice to have that moment and say, 'F-ck you,' a little bit. Not many people get that moment, and I'm really grateful that I kind of had it."
The Bachelor finale will air as a two-night event on Monday and Tuesday next week, and Caroline teases that fans will understand her pain once everything unfolds on TV.
"You'll see what happens," Caroline said.
"I used to think highly of him, and I feel like I've seen a different side of him. The side where there aren't any lights or cameras, and you're behind closed doors, and you think you're safe. He called [Krystal Nielson] out for what she said when no one was watching. He's a little hypocritical!"
Caroline told People that Arie seemed to treat the "whole experience" of being the Bachelor as a way "to live vicariously through something other than racing."
"Look at the facts and how things went down. It's personal for me. This isn't just a TV show," she insisted.
"This is real life, and it's funny because you kind of don't feel like it because it's a whirlwind. But at the end of the day, it is real life, and there are consequences, and people do get hurt. I wish he realized how much power he had -- and I wish he hadn't abused it."
Caroline hopes Arie will turn over a new leaf once The Bachelor wraps, because if he is currently in a relationship, she believes his girlfriend or fiancee deserves better.
Caroline told People she wants Arie to "move past the glitz and glam of being the Bachelor and actually take it seriously."
And Caroline promises her issues with Arie have nothing to do with bitterness or resentment considering they dated on the show and he broke up with her.
"It's funny because it was never about me and Arie. It was always about these girls. We became friends," Caroline clarified.
"My relationship with Arie didn't develop as fast as anyone else's. There were times when I really cared about him. When I left I said, 'No hard feelings, I think you're a really great guy and you're lucky you have really great girls in there. I wish you nothing but the best and I really hope you find her.'"
Caroline's feelings have clearly changed since then!
