I think it's kinda obvious. A guy pretty much threw this girl away, one who was probably willing to love him and give him the world if he asked for it. She decides that she'll keep going on with her life because she's better than that. In the end, he'll realize how stupid he was and he'll want her back. Thing is she's moved on. He's gonna wish he had her to love, but he's going to hate her for moving on when he can only blame himself for what happened.
