What is this.

You occupy the best of me
The worst of me takes control
Not sure if I'm in love with you
Or the void deep in your soul
It reflects the emptiness in mine
Can you feel the gravity within?
A vulnerable way to live
Exposed by the flaming twin.
It's like a flaying tearing away
All these ways I'd rather not be
I guess I'd prefer it to be you
Who reveals the flaws in me.
