The beautyof songs is we can all take them differently.
I had someone who I have loved for a very long time but we just never tried at a relationship. And I left my hometown cause it was so hard for both of us. He died in a scuba diving accident and this song explains everything, the pain of loving the ghost in front of me, Iv written so many notes some angry, some lovely memories. Iv found a Great man who loves me, and wants me, but my love for him just isn't as strong as it is for my past flame, and it explains the loving a stranger only made me love you more. Its a bittersweet victory knowing someone else who wanted me.
You tried to explain it part is the many times I imagine him, and myself trying to explain why all f this could have happened, all the dreams I have of him and were together again, but in the end he dissapears.
You really can't laugh, you can't cry. You just are. After you lose someone you love, you become emotionless.
And all you can do is get use to the pain.
