[Verse]

 F                                G          Am          
Tell you that I love you, that I can’t hold back.
       F                             Em            Am
The feeling that you give me, wanna give it right back.
 F                                G       Am
I know you always win at this particular game, 
    F                            Em          Am
I need to know the rules if you want me to play.


[Chorus]

F                        Am  G
You treat me like your boyfriend
F                   Am
And trust me like a

[Verse]

      F                           G     Am  
I’m trying to be honest ‘cause I can’t relax
  F                             Em        Am
When I get around you, I can’t hide the fact
   F                                G       Am
I let you take advantage 'cause it felt so good
    F                           Em       Am
I blame myself for thinking we both understood

[Bridge]

     Am                                 F     
Don’t wanna, don’t wanna play the crying game
        C        G
Do you feel the same?
     Am                                 F
Don’t wanna, don’t wanna spin the bottle again
