A Heart is Not A Toy

Why is it that you had to play with my heart 
you used me and its tearing me apart 
You got what you wanted and decided we were throuhg
how could you do this to me, I was good to you 
I gave you everything and got nothing in return 
If I couldn't see it then Im never gonna learn 
Why is it that I was too blinded to see 
that you never really cared for me 
Dont you feel guilty or bad for what you've done 
You hurt me so deeply, I thouht you were, "The one" 
I thought you were different from the rest of the guys 
You were just like any other, you spoke in lies 
you never really meant anything you said 
your words were just a ploy to get me in bed 
and if that didn't work you would go to"plan B" 
You would lay on the guilt with,"Dont you love me?"
Dont you know a heart is not a toy 
Why did I ever give mine to a boy? 
If I ever fall in love again I'll help it if I can
before I give my heart away, I'll make sure he's a man
