As The Bachelorette Desiree Hartsock continues to narrow down her suitors, the men are realizing the huge commitment they signed up for: they'll have to get down on one knee and propose -- even though they've only known Hartsock for a few weeks.

In the real world, that sudden commitment might raise some eyebrows. However, on a national TV show, a proposal is expected because the show needs a happy ending. So what exactly is going through the guys' minds leading up to the final rose ceremony? Former Bachelorette season 4 winner Jesse Csincsak spilled the details about the days leading up to the proposal.

"One morning you wake up, and ABC producers take you to a room with a bunch of engagement rings," Csincsak told EnStarz. "You're like, 'Holy crap! I cant afford a $60,000 wedding ring.'"

The show pays for the ring, telling the men that price isn't an obstacle.

"Producers are like, 'Just pick one. You don't have to pay and so you do," he revealed. "Then you leave, go outside and throw up."

After that everything is just a blur, the season 4 winner said. The men, despite having any reservations, must propose, as it's part of the original contract they signed. Speaking about the final rose ceremony, Csincsak admitted: "It feels like being on vacation. It is like, 'Wow, this is fun.' Then the cameras go off, and you have ten minutes to think about what just happened."

"You're like, 'Wait a minute.' Pinch yourself and go, 'Am I awake? Is this real life?' and yep, your engaged."

After filming ends, the pair must keep their romance as secret as the episodes begin to air on ABC. The Bachelorette star and her fiance keep everything under wraps by meeting in secret locations set up by the show's producers.

"Every season is different, but on my season I was flown to a different secret location in the Hollywood Hills to meet up about every ten days," Csincsak revealed.

Csincsak broke up with season 4 Bachelorette Deanna Pappas in 2008 and knows from experience that after the show ends, most of the relationships do too.

"The couples are just kept so busy in front of cameras at red carpets and events after the show is over that they don't have time to break up," Csincsak explained, adding that most couples stick together for the money -- but after the fame and cameras fade so does the romance.

The Bachelorette airs on Monday nights at 8 p.m. EST on ABC.
