I believe this about someone who is giving everything into a relationship and he continues to try and keep pushing forward to make her happy. The Lines in the chorus seem to be someone who keeps being there for someone because of how much the love them but they know that after it all it will just go back to something he doesn't want. He really wants things happen again and he understands what hes doing to himself chasing somebody who just wont be there.
