The Bachelor is now down to six contestants and while Juan Pablo Galavis has been breaking hearts during eliminations/rose ceremonies, a contestant is said to turn the tables on him and quit the show, leaving him "shocked."

Juan Pablo Says He'd Rather End Up Alone

"Juan Pablo was devastated. The woman was a frontrunner. If she hadn't left, the outcome of the show would have been very different...He didn't want her to go, and he was completely shocked that she left," a source told Us Weekly.

Word is that the girl who is set to walk away from the show and Galavis is Sharleen Joynt.

Galavis took the contestant on a one-on-one date where "they get very physical" and she opened up to the idea of not focusing so much on her career so she could marry him and be the step-mother of his four-year-old daughter, Camila. However, when she returned back to the hotel in Miami, she changed her mind and thought it was too soon for him to meet her family.

"That was the next step, and she didn't feel comfortable doing it, so she decided it was the right time to leave...She [told Galavis] she didn't know if her feelings had developed to the point where she was ready to accept a proposal. [She said] 'I don't want to take the spot of someone else who knows they're at that place.'"

Galavis reportedly held back tears and told her it was alright.

While he said he "really wanted" to meet her parents in an upcoming episode, she is said to only have been attracted to his looks.

The insider added, "Her attraction to him was pretty much physical. She is used to dating more challenging guys, and she and Juan Pablo didn't have a lot to talk about."

Tune in to the newest episode of The Bachelor Monday Feb. 17 at 8/7c on ABC.
