Intro: G Cadd9 Em D Cadd9

G                             Em
I told you my heart's leaning toward you,
Cadd9
A little more, then I knew,
G             D       Cadd9
Something was scaring you,
G                                 Em
Is it too much or too fast or too forward,
Cadd9                      G
Should I step back, and pretend,
        D            Cadd9
I don't feel this way.
Am
I don't wanna tell a lie,
D
I don't wanna have to hide,
            G
It's on the line, 
                  Cadd9
I've waited for a sign,
                 Em
I see it in your eyes, 
   D                          Cadd9
I, I know you really feel the same,
          G
I need to know if,
                  Cadd9
I should raise or fold,
                     Em
My heart is stuck on hold, 
  D                         Cadd9

From anything you say,
G                            Em
You make me feel nervous and stupid,
Cadd9
Whenever I tell you,
    G        D       Cadd9
I'm tired of playing games.
Am
I don't wanna tell to lie,
