(When asking if he likes me back) Does not really mean absolutely not (and their just trying to be nice) or is there still a chance?

I had a crush on this guy and my friends asked if he liked me. He said not really. If he didn't like me wouldn't he just say no? Is there still a chance that he might like me? or does he mean striaght up no, but is trying to be nice?
