Simple Mistake

I bet that youll sleep great tonight without me in this place,
I already forgot that night yeah It was yesterday,
I bet that It was hard for you,
so hard to let me down,
the hardest part of giving up means I wont be around,

I know Ill forgive but Ill never forget,
the fact that you couldnt decide,
well see how it ends but Im sure youll regret,
those words that youve left behind,

I cant sleep tonight and I wont dream again,
And Im waiting for you to stop acting like them,
it was a simple mistake,
you should have never of taken my heart,
letting you go, letting you go,

I bet that Im not .. now,
I bet that youve moved on,
what happens when the music fades?
What happens when shes gone?
I bet that you thought I was wrong,
I bet that you are right,
I know that I should leave this town,
yeah Ill be gone tonight,

tonight the lights will turn red and youll stop and wonder,
what used to be then is now lost cause you found her,
I promise you this and Ill leave you alone,
promise that youll understand,

I cant sleep tonight and I wont dream again,
And Im waiting for you to stop acting like them,
it was a simple mistake,
You should have never of taken my heart,
Letting you go letting you go,

Youll see what your missing when your reminiscing,
I know all the times that never came back,
youll see that youre wrong,
and youll see that this song is about you and youre not about to be getting me back,

I cant sleep tonight and I wont dream again,
And Im waiting for you to stop acting like them,
it was a simple mistake,
you should have never of taken my heart,
letting you go letting you go
