V1
I'm done wondering where you've been
All night long when you're out with your friends
All you say, that the matter's over
But now that chapter's over

I'm done trusting you it's ended
Even after I catch you red handed
You could've been my only one
But now your chance is gone

Chorus
You should've when you could've
You're gonna miss my love girl
You should, it would've been so good
You should've when I would've
Now I know I've had enough
Better luck next time girl
You should, it would've been so good

V2
I'm done chasing you all over
May as well be chasing after thunder
Play hard to get if it makes you happy
For a change now you can start chasing me

Don't cry cause I ain't your sure thing
It ain't my fault you don't know a good thing
You could've been my only one
But now your chance is gone

Bridge
Don't you understand
Don't wanna be your backup plan
Now I won't be here to clean up when it hits the fan

You tried to keep me on your leash
It's time you started chasing me

V3
I'm done acting like I won't be
Sitting here still wishing you wanted me
Don't say that I never told you
Take some advice from somebody who knows

(John L. Cooper)
