The Ex(2007)

Tom Reilly is a bit of an underachiever when it comes to his career (or lack thereof), but his adoring wife Sofia, a formidable lawyer, has always been happy to act as the breadwinner. With the birth of their first child, Sofia decides she wants to be a stay-at-home mom, so Tom needs to step up and take care of his growing family. Unfortunately he gets fired from his job in New York City and is forced to start working with his father-in-law in Sofia's hometown of Ohio. Tom soon clashes with his work colleagues, especially the outrageous Chip, who still carries a torch for Sofia from their high school days, and Sofia becomes increasingly uncomfortable staying home with their new baby. In doing all the right things for all the wrong reasons, the couple needs to get back to what they're good at, before their model family goes completely off track.
