Ex-girlfriend.

Your wildness scares me
So does your freedom
You say you can't stand the restrictions.

I kinda always knew I'd end up your ex-girlfriend
I hope I hold a special place with the rest of them (all the time that we wasted)
I kinda always knew I'd end up your ex-girl, friend...

I'm another ex-girlfriend on your list
But I should have thought of that before we kissed.
