Not now, Not ever

(Pleaze comment on my poem)

You ripped my heart out
Left me there to bleed
Then you come back?
Looking for what use to be?

I don't need your immaturity
I'm doing fine on my own.
I can tell by your personality
you haven't grown,

You think you can have me?
Well you cant and never will
So just give it up
Because years from now I will hate you still.
