Dm
At a party yesterday
        Am
Saw the room where you and me
          Gm
Had some fun, you thought it was love
          Bb7M                A
Now I'm stuck here reminiscin'

       Bb7M           Am
And I try day and night
       Dm      Am    Bb
Oh, to somehow draw a line
      Bb7M             Am Gm A
Wanna cross it all the time

                      Dm
I think I'm mentally cheating
                       Am
How could I be so disobedient?
                               Gm
I'm just eighteen, don't have experience
                                  Bb7M        C
Can't help the fact that I caught feelings, oh-oh
                       Dm            C       Bb7M
I think I'm mentally cheating, oh, cheating, cheating (oh)
                       Dm           C        Bb7M
I think I'm mentally cheating, oh, cheating, cheating
                       Dm
I think I shouldn't be lookin' in those eyes
             Am
Why do they give mе butterflies?
   Gm             Bb7M
Can't exprеss how obsessed
      Gm            A
Is it purely the attention?
         Dm
I'm just tryin' to decide
      Am
If I stay, I'd have to lie
    Gm           Bb
To myself, feels like hell
        Gm                  A
To be in love with someone else

      Bb7M        Am
And I try day and night
        Dm     Am      Bb
Oh, to somehow draw a line
       Bb7M            Am Gm A
Wanna cross it all the time

                       Dm
I think I'm mentally cheatin'
                     Am
How could I be so disobedient?
                                 Gm
I'm just eighteen, don't have experience
                             Bb7M            C
Can't help the fact that I caught feelings, oh-oh
                        Dm          C        Bb7M
I think I'm mentally cheating, oh, cheating, cheating (oh)
     Bb7M              Dm          C         Bb7M
I think I'm mentally cheating, oh, cheating, cheating

    Bb7M               Am
So goodbye, I'm out of time
      Dm             Bb7M
Only said I love you twice
        Bb7M           Am
I know that it's not a crime
       Gm              A
I need more to keep you mine
     Gm           Am
So goodbye, it's alright
       Dm     C      Gm
Baby, it's a part of life
     Bb7M              Am
Something's gotta sacrifice

                      Dm
I think I'm mentally cheatin'
                      Am
How could I be so disobedient?
                                   Gm
I'm just eighteen, don't have experience (I'm just eighteen)
                             Bb7M           C
Can't help the fact that I caught feelings, oh-oh


I think I'm mentally
          Dm           C         Bb7M
Oh, oh, cheating, oh, cheating, cheating (oh)
          Dm           C         Bb7M
Mentally cheating, oh, cheating, cheating
                       Dm
I think I'm mentally cheating
