Roslyn's J.P. Rosenbaum won the heart of dental student Ashley Hebert on Monday night's season finale of ABC's "The Bachelorette," besting Sonoma, Calif., winemaker Ben Flajnik.

"Today is the reason I went through all the good times and bad times," Hebert said as Rosenbaum prepared to propose. "And I've been wanting to tell you how much I loved you for so long now. . . . I do not want to be with anyone else but you forever."

Hebert, 26, of Madawaska, Maine, now studying at the University of Pennsylvania, first had to overcome the objections of her sister, Chrystie, who flew in with family to Fiji to meet the final two men.

Though Hebert had said, "I don't think there's anything that J.P. could do that they would feel like he wasn't right for me," the divorced, heavily tattooed Chrystie, told her, "I don't think he's the one . . . I think you're too young and I think you're too spunky and he's just kind of a little bit older and a little bit more demure" -- all of which brought Hebert to tears even though their mother said Rosenbaum seemed perfectly fine.

Chrystie stung Rosenbaum himself when she told him she wondered why a 34-year-old "hasn't . . . found anyone yet and what does he want with my much younger sister?"

Hebert later conceded, "I think my family loves Ben and I think they thought he was perfect for me." And she and Flajnik, 28, did share romantic interludes in a mud bath and in a hotel room where he professed his love. Yet she turned down his proposal, and he left heartbroken.

When it was Rosenbaum's turn, he and Hebert each declared their love for each other, and she accepted his proposal.
