Shotgun Wedding. Literally

Inside my head I hear her whisper,
My heart breaks knowing I still miss her.
And even deeper down the vastness of my mind,
I feel as though I left a part of you, in there, behind.

I searched further down my framework, back to a time,
Where I remember crying when I heard the parish bells chime.
I remember at the altar I waited for you (waited for you),
I tried to solve this but I haven't a clue (haven't a clue),
What happened to you, my love, where are you (where are you)...

Then a butterfly gently fluttered through the halo-strewn windows,
Everything went silent except for the river beside full of minnows.
The little darling landed on the corsage on my suit,
Then a scream from afar said "don't shoot!"

All I remember was a figure in black running away from the scene,
Then a woman wearing white, covered in blood, with a teary sheen.
I recognize her but the resemblance was too dreary,
I wish I locked it back away in my head; I'm teary.
