Lyric discussion by liftednevermore 

He's obviously saying that the relationship just doesn't mean the same thing to him as it does to her. Sure he wants and needs her, but it's not love, and it never will be. He even talks of the fact that: "There's only one girl that I will ever love And that was so many years ago And though I know I'll never get her out of my heart She never loved me back" As it once happened to him. Kind of a regretful and sad song, really. About how sometimes it's just not meant to be.

@liftednevermore Or maybe love is fleeting and arbitrary, and that whatever he felt for this girl was going to be good enough for the both of them (two out of three ain't bad).
