[Intro]
D D6
D D6
[Verse 1]
D D6
Too long to call it nothing
D D6
Too weak to call it love
G G6
But I'm hanging off the smallest finger on your hand
D D6
And I'll keep holding on Hmm
[Verse 2]
D D6
Been silent for so long
D D6
Not sure what I'd say
G
Maybe I should keep my mouth shut
G6 D D6
Maybe things should stay this way Hmm
[Chorus]
G G6
I don't want things to change
F#7
Just want this voice to go away
G
That tells me maybe we could be something more than we are someday
I don't want to lose you
G6 F#7
Don't want to scare you away
D D6 D D6
I need to move on but I'm scared that you won't stay Hmm
[Verse 3]
D D6
I looked to you for things
D D6
I knew weren't really there
G
I know I'm being selfish
G6 D D6
I know I'm being unfair
[Verse 4]
D D6
But I'm happy to know you
D D6
Whatever way you want
G G6
I just need some time to adjust to knowing
D D6
This is all we've got Ooh
[Chorus]
G G6
I don't want things to change
F#7
Just want this voice to go away
G
That tells me maybe we could be something more than we are someday
I don't want to lose you
G6 F#7
Don't want to scare you away
Gm D
I need to move on but I'm scared that you won't stay
Gm D
Why would you stay?
