These are the chords I use. If you want you can hit the B and E string.  
Sounds like they barely touch them in the song though. 
The strumming pattern is pretty easy. You'll figure it out. Have fun!

(Intro) 

Aadd9, C#m7, Bm7 (Repeat) 


(Verse) 

Aadd9 
There's only one place that I wanna be, 
C#m7                         Bm7 
It's home with you, girl, so I can hear you breathe. 
Aadd9 
With your hair up like you do, 
         C#m7                  Bm7 
And that face that you give me when you've missed me. 

(Repeat Chords) 
And I've missed our girl so god damn much, 
I've smoked a lot and I feel so rough. 
Guess this is just what I wanna do, 
Keeping half-smoked smokes and singing to half-filled rooms. 

(Chorus) 

Asus2 
I was young and irresponsible  
Bm7 
About a year ago and it's impossible to tell 
Asus2 
If my hands will ever warm up 
Bm7 
I don't believe in growing up but  

(Verse) 

Look at me now, I'm engaged to be married, 
I'm only 23 and I've got myself a family. 
She's not mine and she never will be, 
I'm reminded every day. 
She's not mine and it fucking kills me, 
She won't look at me that way 

(Chorus) 

I was young and irresponsible 
About a year ago and it's impossible to tell 
If my hands will ever warm up 
I don't believe in growing up 

(ends with Aadd9)
