G5                      D5 
Sure I think about you now and then 
C5              C5                 G5 
        but it's been a long, long time 
C5  G5                         D5 
     I've got a good life now, I've moved on 
C5             C5              D5  A5  G5 
        So when you cross my mind 
C5                             G5 
I try not to think about what might have been 
       E5          C5            G5             A5    G5 
'cause that was then and we have taken diff'rent roads 
C5                      G5 
We can't go back again there's no use giving in 
A5                G5            D5   C5 
      And there's no way to know       What might have been  

play intro once then: 

Verse 2: 
 
We could sit and talk about this all night long 

And wonder why we didn't last 

Yes, they might be the best days we will ever know 

But we'll have to leave them in the past. 
 
chorus 
 
Bridge: 
E5 
That same old look in your eyes 
B5 
it's a beautiful night 
C5                      D5    G5 D5 
I'm so tempted to stay  
E5 
But too much time has gone by 
B5 
We should just say good-bye 
C5 
and turn and walk away 
D5                        D5  A5 B5 
chorus 
G5            A5     G5             D5         
                No, we'll never know 
C5              
                what might have been
