In my opinion that beautiful song is about a relationship of the singer who tells the story of the girl he loved most. When they met both knew that they are made for each other and had some great moments. Not those big "love story moments" but something better than that because they shared little and quiet experiences together, full of love and understanding. But I think that both had to fight with their own mental diseases/problems so it was very difficult to handle everyday life and sometimes they just lost theirselves in drugs and alcohol. And as the time went on she couldn't handle the troubles anymore and decided to leave him. While she is getting better he is completly out of control, misses her like hell and tries to get over her but it doesen't work. So after years of suffering she comes back and ask him to be just friends now. Even if it breaks his heart because he will love her forever he consents, just to be with her.
