A simple apology

I have nothing left to say.
It's time for me to walk away.
Cut our ties, break our bonds.
Before you realize it, I'm gone.
I'm sorry that I must depart,
But the weak protect their hearts.
You don't know how close you came.
[We] will never be the same.

So again I glance away,
no, I'm sorry, I can't stay.
Please don't look so upset.
All those nights, I can't forget.
I can't go back, I can't revert.
I can't pretend that I'm not hurt.
I'm sorry.
