girlfriend of a vampire

I walked out of the door
Hoping you were there for me
But you just wanted more
More blood, from me

You kept me like a prisoner
In the chambers of your heart
No, you did not think of me as your life
No, you did not think of me as a work of art

You made me slit my arms
And made me watch you drink and feast
You made me do crimes
And now i feel like a beast

When would you let me go
When would you ever let me free...
