Do I still exist to you?

I carelessly opened the small envelope that sat on the dining room table when I got home from school. The piece of paper inside was folded in half and covered in gold sparkles. On the front it had written in perfect, joined up handwriting was , " Brandon" my name. I unfolded the paper and curiously read what was written on it.

"There are pieces of me scattered across the city, I'm just waiting on someone to put the pieces together, finish the puzzle of my soul and come to me with a finished map of who I was and who I should be . So I chose you, Brandon. Your different from everyone else, it seems like you care, your heart is still so pure. You deserve nothing but happiness and I love you ...
That's right I said it, I love you. Do you want to know why?
Because baby,
Your soul is made of stars"

I stood there paralysed, a single tear danced down face.
It was signed with the name Skylar. I knew exactly who it was, how could I forget her name.
She's the girl I loved.
