Not into you

What happens when your EX is your NEW ROOMMATE?
Once, you were everything that I wanted. After you left, I lost everything.
But then you waltzed back into my life: confident, arrogant, and as dark and as beautiful as ever.
You never cheated and you never lied, but that doesn’t mean that what you did didn’t hurt.
My hatred for you is a fire you’ll never extinguish.
You know this and you take my hand anyway. I want to push you away, but you won’t let me.
What happens when I start to cave?
What happens when all of my rage becomes the opposite of hate?
