He's Just Not That Into You is a self-improvement book written by Greg Behrendt and Liz Tuccillo that was published in 2004. It was a New York Times bestseller and was featured on The Oprah Winfrey Show.
The book was inspired by an episode of Sex and the City titled "Pick-A-Little, Talk-A-Little," in which Miranda asks Carrie's boyfriend, Jack Berger, to analyze the post-date behavior of a potential love interest. Because the man declined Miranda's invitation to come up to her apartment after the date, stating that he has an early meeting, Berger concludes, "He's just not that into you," adding, "When a guy's really into you, he's coming upstairs, meeting or no meeting."
