Love Lasts 3 Years (2011)

A heartbroken literary critic turns his despair into creativity following a bitter divorce, only to encounter an enchanting beauty who poses a major challenge to his newfound cynicism. Marc Marronnier (Gaspard Proust) thought his marriage was going well until his wife (Louise Bourgoin) deemed him immature, and left him for a high-profile writer. Devastated, he began filtering all of his heartache into a misanthropic manuscript decrying the virtues of true love. But later, when Marc falls hard for his cousin's radiant and gorgeous wife, his entire life is turned upside down.
