I kept looking for a tab for this song, and one hasn't popped up. So, I gave it a shot 
I think it's right but you can never tell. Revisions are welcome.

Second Option
By Thad Cockrell and Caitlin Cary

GC
I dont wanna be your second option
GC
I dont wanna be your after thought
GC
I dont wanna know the plans you make
GC
If they're not with me then call 'em off
GC
call 'em off

CAm
Ive been alone on Sunday, baby
CD
Ive been alone on a Monday
CAm
Ive been alone too many days baby
C
Dont you ever doubt it
D
When I can learn to live without it
G
Ill be gone
G  C
Gone

I dont wanna know where you'll be going
I dont wanna see what clothes you wear
I dont wanna hear the full you make
If its not for me then I dont care
I dont care

Ive been alone on Sunday, baby
Ive been alone on a Monday
Ive been alone too many days baby
Dont you ever doubt it
When I can learn to live without it
Ill be gone
Gone
Gone

AmC
The leaves on the trees are lonely
AmD
The stars wanna shine
AmC
If you dont care let go of me
AmD
Too cruel to be kind
AmD
Cruel to be kind

I dont wanna hang on your pretty hook
I dont wanna wait another day
Im the biggest fish in your shallow water
Always be the one who got away
Got away

Ive been alone on Sunday, baby
Ive been alone on a Monday
Ive been alone too many days baby
Dont you ever doubt it
When I can learn to live without it
Ill be gone
Gone
Gone
Ive been alone on Sunday, baby
Ive been alone on a Monday
