B
Doctor, doctor, look what I've done
B                       E/G#           B
Stick me in a house and tell them I'll run
  G#m                    E/G#                B
I run for the hills if I ever try to fall in love again
B
Watch me set this city on fire
B                   E/G#         B
If they ever let me out of their sight
     G#m                      E/G#               B
I'll stay 'til the world goes down if I keep the upper hand

[Pre-Chorus]
C#m                        E
If I could go back, I wish somebody said

[Chorus]
B
Hey now, Casanova
B
I don't wanna mess you up
                      E/G#
But, trust me, if you love her too fast
               E/G#
She won't ever love you back
                 B
You're comin' in hot like Arizona
    B
No, I don't wanna freak you out
    D#/A#        E/G#
But maybe if you love her too fast
               F#
She won't ever love you back (Love you back, my love)

[Verse 2]
B
Doctor, doctor, tell me, what's right?
B
'Cause I've been up and down every corridor twice
      E/G#                                     B
Tryna make it out, but this merry-go-round, it never ends
        B
Yeah, I watched my friends start shacking up fast
B
Thought I should find somebody or I'm gonna be last
    E                                  B
But fuck that noise, that only left me hurt again

[Pre-Chorus]
C#m                            E
'Cause, honestly, I've been so lost in my head, it hurts
C#m                        E
If I could go back, I wish somebody said

[Chorus]
B
Hey now, Casanova
B
I don't wanna mess you up
                      E
But, trust me, if you love her too fast
               E
She won't ever love you back
                 B
You're comin' in hot like Arizona
    B
No, I don't wanna freak you out
                 E
But maybe if you love her too fast
               E              F#
She won't ever love you back (Love you back, my love)

[Bridge]
B            Bsus2
She'll never love you back, my love
B            Bsus2
She'll never love you back, my love
(Oh, no, no, no she won't)
G#m
She'll never love you back, my love
(Yeah, I wish that somebody told me)
G#m
She'll never love you back, my love (Yeah, if you love)
E
She'll never love you back, my love (If you love her too fast, no)
E
She'll never love you back, my love
B
She'll never love you back, my love

[Chorus]
