When Christopher Abbott announced Thursday that he was leaving the HBO smash hit, "Girls," fans were shocked. Even though the show put Abbott -- who plays Marnie's love interest, Charlie, on the map -- he's decided to pursue other career moves.
Despite rumors that Abbott and "Girls" creator Lena Dunham were butting heads over creative differences, a rep for the actor told People magazine that "[Chris] is grateful for the experience of collaborating with Lena, Judd [Apatow], and the entire 'Girls' cast and crew, but right now he's working on numerous other projects and has decided not to return to the show."
