intro: 
G F C C (repeat 2x)

G                     F
You dropped your coat by the door.
C                 C          G     F     C    C
I ran outside to watch you drive away from me.
G             F        C  C
And my eyes, they won't believe.
G                   F       C        C 
My heart is trying desperately to beat.
G F C C

G                          F
And lately I'm speeding up my breathing.
    C                             G
And my hands are shaking all the time.

CHORUS:
               A               C
'Cause I don't want to let you go.
            G                     F
And I can't sleep or breathe when I'm alone.
           C               G
If I could just go back in time,
           F             C                    A               G
I wouldn't make the same mistakes; if I could just go back in time.


G                    F
I'm looking at what we wrote,
C                 C            G      F            C      C
In old postcards, and counting the times you'd repeat yourself.
G     F                C      C
and I, just want to hold you
G            F          C            C
no I just, I just can't let you go. (I Just can't let you go.)


REPEAT CHORUS

G F C  (repeat until fadeout)
