"I really felt like I was going to spend the rest of my life with him. I thought he was my fairy-tale ending," Pappas told In Touch Weekly in a Monday report. "But after the show was over and we settled in to our normal lives, I slowly came to realize that we are two totally different people and it wasn't going to work out."
Csincsak, a 25-year-old professional snowboarder from Breckenridge, CO, had proposed marriage to Pappas during July's broadcast of The Bachelorette's pre-taped fourth-season finale. Pappas accepted and subsequently presented Csincsak with her final rose.
During The Bachelorette: After the Final Rose special that followed the finale, the couple revealed that they'd decided to wed in the Bahamas on May 9. 2009. However, in recent months they had wavered on the ceremony's location.
Despite her break-up, Pappas says that she still has faith she will find the right guy for her.
"I still believe in love," Pappas told In Touch. "More than anything, I want to find someone I can spend the rest of my life with."
Pappas and Csincsak's break-up leaves Trista and Ryan Sutter, who met on the show's first season and were married in 2003 dream wedding that was broadcast on ABC, as The Bachelorette's only remaining lasting relationship. Last month, the couple announced they are expecting their second child in April.
