I think I probably knew from our first kiss
Last night it finally sank in
clmost let the words slip out of my mouth
Swear my heart jumped 'bout 30 feet down in the dirt
I couldn't seem to say a single word

Cause you know when you know that you know
But you don't 'til you do
I didn't wanna jump the gun or speak too soon
Yeah it's about time that I finally see this through
Cause you know when you know that you know
But you don't 'til you do
Wish it was but it just ain't you

Looking back on it now it all makes sense
It was clear as day but I couldn't see it back then
Felt it downtown when you met my friends
Mama didn't say it now I know what she meant with her eyes
She knew what I didn't know until tonight

Cause you know when you know that you know
But you don't 'til you do
I didn't wanna jump the gun or speak too soon
Yeah it's about time that I finally see this through
Cause you know when you know that you know
But you don't 'til you do
Wish it was but it just ain't you

I never wanted to be a heartbreaker
It all looked good on paper
Cause you know when you know that you know
But you don't 'til you do
I didn't wanna jump the gun or speak too soon
Yeah it's about time that I finally see this through
Cause you know when you know that you know
But you don't 'til you do
Wish it was but it just ain't you
Wish it was but it just ain't you
Wish it was but it just ain't you
But it just ain't you
