Lucky Seven (2003)

Instead of really living her life since losing her mother at age 7, Seattle lawyer Amy Myer sticks to a ridiculously-detailed timeline her mother drew as a guideline in all walks of life, even love in search of marriage with 'number 7'. Despite good advice from father Bernie, aunt Rachel, and uncle Ray, she refuses to contemplate going steady with any of her first six steady boyfriends, even apparently-perfect businessman Daniel McCandles. She initially declines to accompany her good friend, bagel-shop manager Connor, to a family wedding as his pretend fiancée, but changes her mind so Daniel can be lucky seven afterward. However, Peter proves to be the perfect match that makes her reconsider the blind life schedule.
