From one to none

I.
I will tell you that you ruined my life
you will tell me that I'm not good enough
one of us must leave
one of us must act as the bad guy
all the ways to hurt you
all the ways to make me cry
none of these will matter
none of these will mean a thing
I know you are my black blue water
you know I am your black green tree

II.
someone has to leave first.
and before you shut the door,
you might as well be the worst.
say that you love me no more
you found somebody else to please you more
let me pretend that I believe you
stay there while I cry.
watch me when I destroy the last piece of you.
feel me hurting you
that's how this story must end.
pain makes letting go easier.
there is no other version of you and me
