Who Are You?

I can't keep putting myself through hell
Just to watch you walk away again

I can't not look at you and wonder so many things
I can't help but wish you were still there

I don't want to let go, like you did
I don't need you here though

I never knew you would be like this
You have done this before I heard

You have changed, I get it
I swear, I get it

You aren't the same person I once knew
What happened to him..

No one knows who you are
Do you?
