Lyric discussion by DementedVampiricZombie 

Alright, I see two possible interpretations of this.

(1) The song is about the singer's first love.

(2) The song is about a relationship that ends in the death of the person about whom the song was written.

I could go through the song line-by-line, but that would take forever, so I won't. But that's how I see it.

My Interpretation

I agree. He is talking about his first love from long ago or he's talking about the death of a relationship at his hands...his choice.
