Things are getting down to the wire in season 18 of ABC's “The Bachelor.” Only six girls remain in the running for Juan Pablo’s heart after the 32-year-old single dad bid an early goodbye to Cassandra (on her 22nd birthday) and sent Kat packing during the week 6 rose ceremony. Renee, Nikki, Chelsie, Clare, Sharleen and Andi are left, but by the end of the episode, fans saw that one of the ladies was seriously doubting her chemistry with Juan Pablo.

“I’m happy to be here and happy to be going on,” Sharleen told the cameras after the episode 6 rose ceremony. “But at the same time, I feel that it’s wrong somehow. I feel guilty in a way.”

Sharleen has been battling with the whole “process” and her feelings for Juan Pablo since the first episode of the season. Week after week he consoles her and tells her how different she is from the other ladies and how much he wants her to be there …. Yet she still doubts whether or not this is the right choice for her.

“To be honest, I can see other girls here suiting him better,” she continued in Monday night’s episode. “I don’t want to hurt Juan Pablo.”

But with hometown dates right around the corner, it’s looking more and more like Sharleen will be breaking the single dad’s heart … similar to what “Bachelorette” contestant Brooks Forester did to Desiree Hartsock over the summer.

For those who missed or don’t remember Desiree Hartsock’s season of “The Bachelorette,” the 27-year-old bridal stylist was completely smitten with Brooks Forester, a 28-year-old from Salt Lake City, Utah. The pair seemed to connect from the first date (in which they dressed up in bridal gear), with Brooks making it all the way into the finale of the show in Desiree’s top three. And while Desiree may have been head over heels, Brooks seriously doubted that Desiree was “the one” for him.

“The idea of me proposing to her at the end of this makes me uncomfortable,” Brooks told his family before the final rose ceremony in Antigua. “I want to be in love.”

Unfortunately, at the same time that Brooks decided to end things with Desiree, the bachelorette was telling the cameras that she’s in love with him and misses him every day when she’s not with him.

The breakup was completely brutal, with Desiree crying and asking him why he chose to end things then. But Brooks couldn’t give her an answer. “I don’t know,” he explained. “I didn’t know before this. I really always felt like I needed more time.”

And while Desiree was initially thrown off (and wanted to quit), things managed to work out in the end. She’s now happily engaged to contestant Chris Siegfried and the two are planning their dream wedding.

But will Juan Pablo get his fairytale ending when “The Bachelor” concludes?

“Sharleen has been an enigma since she got out of the limo,” host Chris Harrison dished to TV Guide about the bachelor’s relationship with the opera singer. “I find their relationship so intriguing. In New Zealand, she didn’t even say hello before he jumped on her and started making out with her. Even she was like, ‘What was that?’ It’s like, ‘I don’t know what to say to you, we have very little in common, so I’m just going to make out with you.’”

“The Bachelor” host believes that Sharleen just keeps getting caught up in the moment – similar to what Brooks went through with Des.

“She keeps riding this and gets caught up in the moment, but then later, upon reflection, she’s like, ‘I don’t know,’” continued Harrison. “After [this week’s] rose ceremony, I started looking at the monitors and saw Sharleen crying, and I was like, ‘What did I miss?’ It’s been so hard to put a finger on her the entire time and I don’t know what it is, but it’ll come to a head and continue in Miami.”

You can catch episode 7 of “The Bachelor” on ABC on Monday, Feb. 17, at 8 p.m.
