Its really easy. Only c+f. The struming pattern I play is (down down up up down up, down 
up up down up) And so on... I hope that makes sense..

I know that you think of me sometimes
     C                           F
'Cuz all I do is think of you at night
C                           F
I know it may take a little time
           C                          F
For you to see you are the love of my life
           C
And I just sing
Do-do-do-do do-do-do-do-do
F
Do-do-do-do do-do-do-do-do
C                       F

You walked up to my porch and you said hi
  C                                 F
I looked into those beautiful brown eyes
C                             F
All you said was "can we go inside?"
           C
And I said "yes"
          F
And so we did
            C
And we just sing
Do-do-do-do do-do-do-do-do
F
Do-do-do-do do-do-do-do-do
C                       F
Do-do-do-do do-do-do-do-do
             C
And we just sing
Do-do-do-do do-do-do-do-do
F
Do-do-do-do do-do-do-do-do
C                       F
Do-do-do-do do-do-do-do-do
             C (Hold)
Now we're in love
