Readers offered love advice on how to know he's not that into you.

Recent research shows that it's easier to tell when a man digs a woman than vice versa, at least when it comes to flirting. After the initial attraction, however, knowing whether or not he's really into you—in other words, "the one" or even "a keeper"—well, that's the million dollar conundrum.

When He's Just Not That Into You, Liz Tuccillo and Greg Behrendt's book about identifying dead-end relationships, debuted in 2006 it empowered confused women everywhere to move out and move on (well, at least it happened that way on Oprah). This "you go, girl" attitude arrived to the big screen Friday, February 6. The movie version has a celeb-studded cast including Drew Barrymore, Jennifer Aniston, Ben Affleck, Justin Long (the Mac guy and Drew's ex) and Scarlett Johansson.

ScarJo—following in the footsteps of actor/singers Will Smith, Britney Spears and Barbra Streisand—also recorded a song for the film. While the single didn't ultimately make the cut into the film, it's on the soundtrack. The soundtrack also features songs from Maroon 5, R.E.M., The Talking Heads, Corinne Bailey Rae, The Cure, Human League, Wilco and more. You can take a sample listen to some of the songs on the He's Just Not That Into You website.
