I don't know What I saw in you

You may think you know me,
but I know you don't.
You may try to tell me who you
think I should be.
Let me tell you loud and clear that
I'm not just here to push around.
I'm standing my ground.
After all these years I've finally
found out just what you're all about.
I can't believe I didn't see what
you were doing to me.
I don't know what I ever saw in you
or why I let you play your head
games with me.
I guess I wanted to convince myself
that everything was OK.
You wanted it your way and you
didnt want to listen to what I had to say.
You claim you love me, but if you
did you wouldnt've broken my heart
and left me behind to fall apart.
