Committed (R, 2000)

Joline (Heather Graham) believes in commitment. When she gets married, she has the ring tattooed on her finger. Less than two years later, when her husband Carl (Luke Wilson) leaves her without telling her where he's going or why, she tracks him down. She parks near his new home and watches him, inadvertently disrupting his relationships with his new girlfriend (Patricia Velasquez) and his boss (Dylan Baker). Joline becomes friends with his girlfriend, Carmen, and gets advice from Carmen's grandfather (Alfonso Arau), ultimately ending up "committed" in both senses of the word.

Joline is less committed to Carl than she is to the idea of commitment. Her sense of herself is so deeply tied up in the idea of permanence that she doesn't stop to think about whether Carl is the one she should be committed to. And after watching this movie, you may find yourself committed to the idea of finding a better (or at least less offbeat) chick flick.
