I think this song was sculpted from the viewpoint of a person in a dying relationship that neither person is willing to fully end. The target of the lyrics is clearly too proud to admit any fault in the failures of the relationship and simply lives their life pursuing whatever pleases them at the particular moment, without regard for whether their actions are hurting the song's protagonist. As such, this protagonist will eventually put an end to the source of this displeasure, realizing that eventually the two parties will eventually be together again in a similarly painful situation.
