Verse 1
          D  A       Em      G
Why am I mad, I don't get it,
                 D      A                     
It seems like every time you give me signs,
     Em        G 
And I miss it!
          D    A
I did it again,
          Em   G
I admit it,
                 D      A
I left you standing there,
             Em      G   
And now I regret it,
             D       A
Seems like every time,
     Em      G
I get the chance,
     D     A           Em     G
I lose my cool, and I blow it,
      D           A
And I get all tongue tied,
 Em       G
Lost in your eyes,
 D     A          Em     G
I'm a fool, and I know it! 

Chorus
D              A
I should've kissed you,
Em             G
I should've told you,
D            A        G 
Told you just how I feel,
D              A
And next time I won't stop,
Em              G 
I'll listen to my heart,
D            A        G
Cause what I feel is real! 
            D     A           Em     G
I should've kissed you,
            D     A           Em     G
I should've told you how I feel,
            D     A           Em     G
I should've kissed you, 
            D     A           Em     G
I should've showed you how I feel



Same for the rest of the song.
