E    B    Cm    A  


[Verse 1]
            E    B            Cm                  A  
How do you know when to let go of loving someone
               E     B      E         Cm        A  
When will the pain just go away and I can be numb
     E                       B  
Feel nothing when I see you out and about
     Cm                        A  
And not feel the nothing that you feel right now
           E                  Cm           A  
How do you know when to let go of loving someone


[Chorus]
                   A                     E  
'Cause all that I know is you're on my mind
                B  
Im down on the floor, drowning in wine
                    A                       E  
And when I breathe in, I still smell your skin
                      B  
And your clothes are hanging, mixed in with mine
             A                   E  
Oh how do I know what I should do
 Em               B         Gm       B  
When all that I know, all that I know
                  E   Cm   A  
Is how to love you


[Verse 2]
            E     B                 C     Em      A  
How do you know when to give up on almost two years
             E                                       A  
When do you stop thinking you'll wait for her to be here
          E                       B  
And when will this guitar not remind me of you
           E                        A  
And yours not be the voice that I hear the world through
            E             B      Cm             A  
How do you know when to give up on almost two years


[Chorus]
'Cause all that I know is you're on my mind
                B  
Im down on the floor, drowning in wine
                    A                       E  
And when I breathe in, I still smell your skin
                      B  
And your clothes are hanging, mixed in with mine
             A                   Cm  
Oh how do I know what I should do
                B         Gm       B  
When all that I know, all that I know
                  A  
Is how to love you


[Bridge]
                       B  
And I swear that I've given it time
          E                          Cm  
But even whiskey won't let it hurt less tonight
    A                               B  
My friends say be strong and that I'll be alright
    Fm                               B  
Oh how do they know when I've tried


[Chorus]
 A                                      E  
'Cause all that I know is you're on my mind
                B  
Im down on the floor, drowning in wine
                    A                       E  
And when I breathe in, I still smell your skin
                      B  
And your clothes are hanging, mixed in with mine
             A                  E  
Oh how do I know what I should do
                 B  
When all that I know, all that I know
You're still all that I know
                       E                Cm  
So all that I know is how to love you


[Outro]
                 A    E  
Oh, how to love you
 B          Cm     Em           A  
All that I know, all that I know
                                E  
All that I know is how to love you
