i think this song implies that he was trying to find someone and show them that he wants to salvage a relationship by all means "i drove on every interstate" but depsite his effort that person doesnt feel the same, and doesnt need him at all..and because of that, he tells him self "i dont need you" and even though hes "so afraid" by being without this person the only closure he has to help him move on without this person and "run(ning) away tonight" would be that "anyways, it's over, over, over tonight" and he is finally very focused on leaving by ending the song with "tonight i am, i am, i am" i feel he needs to hear it from his own voice in order to really feel confident enough to do it.
