I think this song is about a relationship that is nearing it's end, but the guy can't decide whether to let it go or give it a second chance. He's saying: "You push me out again, you push me up against a wall." I think what he's saying is that this girl is pushing him away, and he has the sense to be afraid (to leave and to be alone) but he also has the sense to a be a fool (to stay, and pretend it's working) and he's "on the fence, to make you stay (with him so it's his fault no hers) or to be cruel (and let her go).
