Gm
I should have known,
That it would end this way,
               Cm
I should have known,
There was no other way,
                 A#
Didn't hear your warning,
Cm                  F
Damn my heart gone deaf.
               Gm
I should have known,
Look at the shape you're in,
               Cm
I should have known,
But I dove right in,
                  A#
One thing is for certain,
Cm                F
As I'm standing here,
               Gm
I should have known.

Gm   F    A#   F   C
Lay your hands in mine,
Gm    F A#   F    C
Heal me one last time,

Chorus:
            Cm               Gm
Though I cannot forgive you yet,
         Cm              Gm
No I cannot forgive you yet,
     A#                C
You leave my heart in debt

I should have known,
I was inside of you,
I should have known,
There was that side of you,
Came without a warning,
Caught me on a unaware,
I should have known,
I've been here before,
I should have known,
Don't want it anymore,
One thing is for certain,
I'm still standing here,
I should have known.

Lay your hands in mine,
Heal me one last time,

Chorus:
            Cm               Gm
Though I cannot forgive you yet,
         Cm              Gm
No I cannot forgive you yet,
     A#                C
You leave my heart in debt
        Cm              Gm
No I cannot forgive you yet
        Cm              Gm
No I cannot forgive you yet
     A#                C
You leave my heart in debt
               Gm
I should have known

Gm             F/A
Maybe you was right,
A#             F
didn't want a fight,
                C
I should have known,
Gm                F/A
Couldn't see the signs,
A#                F
Couldn't see the light,
                C
I should have known,

Chorus:
No, I cannot forgive you yet
No, I cannot forgive you yet
You leave my heart in debt
No, I cannot forgive you yet
No, I cannot forgive you yet
You leave my heart in debt
No, I cannot forgive you yet
No, I cannot forgive you yet
You leave us all in debt, I should have known
