VERSE
A5
Another sleepless night I can't explain 

F5
Somebody said they heard me call your name. 

G5                                 F5
The radio won't let you leave my mind 

G5                                 F5
I know it's over , but I don't know why. 

CHORUS
C5                                  G5                                  F5
Should've known better than to fall in love with you 

      D5
Now love is just a faded memory. 

C5                                  G5                                  F5
Should've known better, now I'm a prisoner to this pain 

      D5                                               C5 F5 G5
And my heart still aches for you. 

VERSE
A5
There was no risk that I wouldn't take 

F5
Not a promise that I didn't make. 

G5                                 F5
All I asked was that you just hold on 

G5                                 F5
And now I'm wondering what I did wrong. 

CHORUS
C5                                  G5                                  F5
Should've known better than to fall in love with you 

      D5
Now love is just a faded memory. 

C5                                  G5                                  F5
Should've known better, now I'm a prisoner to this pain 

      D5                                      C5 F5 G5
And my heart still aches for you. 

BRIDGE
F5
I gave you all of my body and soul 

F5
Never believing we might lose control 

F5
I took my hands off the wheel. 


VERSE
A5
I can't remember if the lies were true 

F5
It's been a million years since I touched you. 

G5                                            F5
I thought time might help me win this game 

G5                                            F5
But being away from you is slowly driving me insane. 

REPEAT CHORUS TO OUT
