i think, this songs is refering to a couple.. she's still in love with him, while he is ready to leave. he's telling her to move on and not dwel on what just happened. to just leave him in her past. she still wants him in her life and she probably feels as if she can't live, or go on without him there. "You shouldn't hang on. It's already gone." she wants something that doesn't exsist anymore....
