To me, this song is about an emotionally uneven sexual encounter, where the girl expected a bit more... "wish I knew what you were looking for... might have known what you would find". The narrator is depressed, lost in life, and is looking out for himself... but nonetheless considers this encounter to be a significant and deeply emotional moment, but did not realize that the other person expected more and ended up hurt.
