Now that you're gone

This is for you, this is for me
You said you would never leave
But now that your gone
I think about you
Way more than I really need too
This is what happens when you turn
Into the Dark Knight
You disappear, out of sight
You left me alone in the dark
Without a light
You made me fight on my own
That hurt, being stabbed,
And dragged down without
You by my side.
You promised to stay, but what
Is a promise if you can't stand by it?
