In this song, John is talking about a relationship that he was in that just couldn’t seem to work out. They’ve tried multiple times to work things out, but in the end, they always seem to just break up, and later on, get back together. After the last time, John was certain that they were done, but now that she has come back, like always, he does not know what to do, because whether they try or not, all they ever do is say goodbye.
