Confessions of an American Bride (2005) on Netflix

Young career woman Samantha 'Sam' Hoyt gets swept off her feet by Benjamin 'Ben' Rosen, who romances her better than anyone before, so she jumps at the offer of becoming his fiancée. If Ben thought a girl's typical obsession with the perfect wedding was testing, she soon proves a particularly bad case; and before he gets used to that, meeting each other's parents complicates things gravely, as Jewish and church wedding traditions don't exactly mix easily. They take their time preparing while living together. Then fate strikes again: the key man from the client of her firm's advertising campaign is Luke Stinson, the perfect guy at college whom she could never date because of a rather serious fall just when they could have kissed. Luke proves still as irresistible, gorgeous, charming, easy-going and simply too sexy for any female not to lust for at first sight, and actually confides in her he asked for her on the campaign because he considers her the one attractive girl who got away. They collaborate intensively while the ever trying wedding preparations continue, and she feels ever more attracted to the love of her youth, so is she still quite sure Ben is truly the love of her life?
