Whole song is C to G To Am To F until the Bridge 
which is

F                  C
I really hope you understand
                          Dm 
That if you wanna take my hand
                                  C
Then you should put yours over my heart 
                                 F
I promise to be careful from the start 
                             C
I'm trusting you with loving me 
          F
Very very carefully 
              Dm
Never been so vulnerable
                   C
Baby I'll make you comfortable
