Robert Pattinson

Is Robert Pattinson afraid to admit he is dating Kristen Stewart, are they having a "no obligation relationship"? Because it becomes a little bit frustrating to find out every day a different story about the 'Twilight' stars. For example, in December's issue of Vanity Fair Magazine, Robert gives a full interview in which the actor claims he and Kristen are “good friends.” What about sharing the same room  in Canada, and all the going out part?
"[We're] good friends. I think she's the best young actress around. She’s influenced how I've done all the 'Twilight' stuff. It's quite nice to have someone who is genuinely indifferent to the whole spectacle of everything", the 23 years old actor declared for Vanity. Should we believe him?
