I ain't youre fool..

You had me
You lost me
You're wasted
You cost me
I don't want you here, messing with my mind
I've realized in time 
That my eyes are not blind
I've seen it before
I'm taking back my life
 
You tried to trade on my naivete
But the things you do and say embarrass me
See once upon a time, I was your fool 
But the one I leave behind is you
