[Verse]
G                      D/G              C/G
Sure I think about you now and then
         Cm/G                     G     C/G
But it's been a long long time
G                        D/G            C/G
I've got a good life now I've moved on
        Cm/G         D       Am  G/B  C
So when you cross my mind
 
 
[Chorus]
I try not to think about
     G
What might have been
       Em7            C
'Cause that was then
            G/D             Am   G/B
And we have taken different roads
C
We can't o back again
G/B                       Am
There's no use giving in
            G/B        D     C2
And there's no way to know
 
What might have been
 
[Intro]
 
[Verse]
G                                D/G              C/G
We could sit and talk about this all night long
           Cm/G           G         C/G
And wonder why we didn't last
G
Yes they might be the best days
D/G                    C/G
We will ever know
                  Cm/G              D      Am  G/B
But we'll have to leave them in the past
 
[Chorus]
C
So try not to think about
G
What might have been
       Em7              C
'Cause that was then
             G/D             Am      G/B
And we have taken different roads
C
We can't go back again
G/B                          Am
There's no use giving in
            G/B        D       C2
And there's no way to know
 
What might have been
 
 
[Bridge]
 
Em                         Bm
That same old look in your eyes
                  C
It's a beautiful night
                   D       G  D/F#
I'm so tempted to stay
Em                         Bm
But too much time has gone by
                       C
We should just say goodbye
                  Dsus
And turn and walk away
 
 
D  Am7  Bm7
 
C
And try not to think about
      G

        Em7          C
'Cause that was then
             G/D             Am    G/B
And we have taken different roads
C
We can't go back again
G/B                        Am
There's no use giving in
            G/B        D     C2
And there's no way to know
                      G
What might have been
 
 
Am   G/B        D     C
No we'll never know
 
What might have been
