OH, CRAP!
Why don't you just leave?! You're good at that. Just go! I have waited almost 4 years for you to come back to me, and when I finally get to the point where I never want to see you again, you walk through the door!

But I'm much stronger now. It'd take a lot more than just showing up to change my mind. And don't bother apologizing. There's nothing you can do to take back what you did. Do you realize what I went through, losing all the trust we had?

I have nothing more to say to you.
Except...gotcha. ;)
