Unsent Message

I don't want to leave,
but its too hard to stay.
Your love is too cruel,
I have to walk away.
You say that you love me,
So why do you cheat?
To your expectations,
I just can not meet.
Your like the air I breathe,
your something I need.
But I can not be,
this so called you and me.
You think that you know me,
the things that I do.
But you don't know me,
you aint got a clue.
I sit in my room,
alone and afraid.
I feel so dirty,
I feel so betrayed.
I am sending you this,
so you may one day know,
that this is the reason,
I had to let you go.
