I don't think it's about revenge at all, really. I think the point of the song is, he really cares about the gal, he wants her, but in the end he knows it just isn't possible. He wants her to come back to him and be with him, but he also realizes that it wouldn't work and that, other then being apart, everything is going well and it would be best not to disrupt that, despite strong feelings. Kind of a right person, wrong time thing.
