What am I supposed to do when the best part of me was always you?

I'm still alive but I'm barely breathing
Just praying to a God that I don't believe in
'cause I got time while she got freedom
'cause when a heart breaks no it don't break even

Her best days are some of my worst,
She'll find a man and a man who's gonna put her first
While I'm wide awake she's no trouble sleeping
'cause when a heart breaks no it don't break even
What am I supposed to do when the best part of me was always you, and
What am I supposed to say when I'm all choked up and you're ok
I'm falling to pieces yeah
I'm falling to pieces

They say that things happen for a reason
But no wise word's gonna stop the bleeding
'Cause she's moved on while I'm still grieving
And when a heart breaks no it don't break even, even ohhhh
And what am I gonna do when the best part of me was always you
And what am I supposed to say when I'm all choked up that you're ok
I'm falling to piecesx3
I'm still alive but the other one's leaving
'Cause when a heart breaks no it don't break even

Oh you got his heart and my heart and none of the pain
you took the suitcase - I took the blame
Now I'm trying to make sense of what little remains
Oh cause you left me with no love in order to remain
I'm still alive but I'm barely breathing
Just praying to a God that I believe in
'Cause I got time while she got freedom
'Cause when a heart breaks no it don't break no it don't break no it don't break even

And when a heart breaks no it don't break even, even
And what am I supposed to do when the best part of me was always you
I'm falling to pieces x3
I'm still alive but the other one's leaving.
I'm falling to pieces
'Cos when a heart breaks no it don't break even
Oh it don't break even no, it don't break even no
It don't break even no
