The international bestselling dating guide by the writer of Sex and the City, now adapted into a hotly anticipated movie starring Jennifer Aniston and Ben Affleck. This hilarious, playful, but honest explanation of male behaviour from a writer and a consultant of Sex and the City, is designed to stop women wasting their time chasing after men who aren't into them, and help them to move on and find men who really are. The line, 'He's just not that into you', was developed out of a conversation between Greg Behrendt and his fellow female SATC writers when they asked his advice one day.

It became an episode which struck a powerful chord with viewers. Now a hotly anticipated movie with an all star cast that includes Jenifer Aniston, Ben Affleck and Scarlett Johansson and produced by Drew Barrymore.
