I believe this song is about a strong unrequited love and the feeling of regret that accompanies it. The narrator sees a girl and wants her, thinks about her constantly, but is unable to have her. Then he realizes what a waste of time the pursuit was and that she's just another girl ("She's not so special so look what you've done boy"). As for the last part, the narrator portrays himself as a sort of Christ figure who has done everything for this girl, sacrificed everything he was, hoping that she finally realizes all he has done for her.
