Danielle Lombard's Bachelor in Paradise experience had a rough ending due to Dean Unglert's pursuit of Kristina Schulman, and it appears "DLo" has some hard feelings about the situation.

"I'm definitely frustrated with him. I think he's been very dismissive of our relationship and continues to allude that he only pursued me because of my looks. I've never been in a position or a relationship where I've felt so disrespected by someone," Danielle told Us Weekly.

As viewers saw on the September 11 finale of Bachelor in Paradise's fourth season, Danielle and Dean left the Mexican resort separately because he decided he was in love with Kristina, who had quit the show days earlier when Dean first determined that Danielle was the girl he wanted to date.

"We left in separate vans to go back to the hotel," Danielle recalled of the moments after Dean said goodbye to her at Playa Escondida in Mexico.

"It's funny because when I pulled up, there was another car in front of me and I was like, 'I bet that's Dean.' Sure enough, he gets out. I was like, 'Screw this guy.' I got back to my hotel room and I think it was five minutes after I put my bags down that I got a phone call from him. I didn't want to talk to him at all. I hung up on him several times before actually staying on the line."

Dean had been juggling Danielle and Kristina for most of the season, going back and forth emotionally and physically between them. One minute, he was making out with Danielle in the pool and gushing about her gorgeous looks, and the next minute, he was apologizing to Kristina for being a jerk and claiming they had a deeper connection.

"I gave it to him straight," Danielle said of her phone conversation with Dean at her hotel.

"I said, 'You don't know what you want. You made a complete fool of me on national television. You literally told me you loved someone else and now you're calling me saying you want to hang out. I just don't understand your thought process. He told me that he was encouraged to say those things."

The 27-year-old nail salon owner from Los Angeles told Us that Dean had an excuse for everything.

"I just think it was his way of saving face at the end of Paradise. He came over to my hotel room and we talked some more. As soon as we got back to L.A., we hung out with each other and started this off camera relationship that I thought was going in the right direction," she explained.

Danielle said it was her understanding that Dean wasn't talking to Kristina anymore, although the Russian dental hygienist seemed to think the same thing about Dean's relationship with Danielle post-Paradise.

"I told him my main thing when we were dating was that I didn't want Paradise to continue after the show. 'If you're still talking to Kristina, then you need to talk with Kristina. But if you want to focus on our relationship and see where it goes then you need to cut that communication off.' I don't believe he was hooking up with anyone else," Danielle explained.

"But I think he was very good at making sure that we weren't saying we were boyfriend and girlfriend or in an exclusive relationship."

During a couple of recent public appearances Dean made after Paradise wrapped -- such as The Ellen DeGeneres Show -- he expressed how he still has real and genuine feelings for Kristina. In turn, Kristina has suggested she'd give Dean another chance as long as he learned from his mistakes.

"Dean is the kind of person who changes his mind every couple of days, maybe even every couple of hours," Danielle sniped. "He doesn't really know what he wants."

Danielle even accused Dean of just wanting to sleep with her before running back to Kristina during the live finale taping.

"It's frustrating because he told me he would have my back and stand up for me but at the end of the day, he just saves himself instead of being honest about things. It's a lesson learned moving forward... I don't hate him but I am disappointed," Danielle admitted.

The brunette beauty, however, said she doesn't hold anything against Kristina.

"In terms of a friendship, I think it's where we were post-Bachelor and before Bachelor in Paradise. We hang out with a lot of the same people but would her and I ever hang out one on one? No. It's not to say I don't like her. Some people you get a lot with more than others," she explained.

As for why Danielle chose to appear on Bachelor in Paradise this past summer to begin with, she confessed she was "honestly hesitant" about the opportunity.

"The way the producers made it seem like there was greater opportunity to meet someone that you could have a relationship with outside of the show," she said.

"I was honestly hesitant to do Paradise because of the stigma it has of it being like spring break and everyone is hooking up. But everyone I talked to that did the show, whether they had a great edit or not, said it was an incredible experience."
