Who are you

Who are you
i thought i knew you
from head to toe
from what you thought to what you said
what you like and what you hated

i thought you were the one person i could cry to
whom i could laugh with
someone i could trust with out a worry

but

you only used me to get what you wanted
now i wonder when ever you talked about life was it true or just a lie like you

you told me never to trust anyone
now i know why

i guess i don't know you
the question still remains unanswered
who are you?
my friend or my enemy
