I figured out the little riff on piano, but I haven't tabbed it on guitar. But here are the notes:
C D E    G    E D C A  C D   G   F   E   C D E   G   E D C A   
A C D   E  D  C   C   C   C E D C  A   A  A  A

Intro chords: F   Am   G F C   F   Am  Am G C

           Am    G        C               F        G     C
And I can't nail down the feeling in this song without a reason
           Am     G         C           Gsus4    G
'Cause the hollow words I'm singing are for you
          Am      G     C               F           G     Am
And I keep trying to remember all those little things you told me
           G
When you'd hold me

F                               C
"Baby, I can't give you all I'd like to
F                                 C            E
But everything you'd need, I will provide you ohh
    Am                            F
And if you feel the world outside denies you
       Am                            F                         
I will fight away the loneliness and emptiness that bind you
E                             F
  From this world, I'll never hide you
E                            F              G
 'Til the day my arms you'll slide through, baby boy

C                                   G        F
One of these days the world is gonna find you
             G         C
And take you away from me
                     G        F
The lights are gonna blind you
               G    C
Gonna make you complete
                        E
A girl is gonna hurt you
                         Am   G    F
A woman's gonna set your heart on fire
     Am   G    F     
Your heart on fire"

F   Am   G F C   F   Am   Am G C

        Am    G        C                   F          G      C 
And if I nail down the feeling, still this song's without a reason
           Am               G            C
'Cause the hollow words I'm singing just for you
           Am     G     C             F         G       Am
And I keep trying to remember all the little things you showed me
            G
When you'd hold me

  Am                           G
I close my eyes for a little while
                       Am
I'm a child, you're beside me
           G
And you're singing...

 F                       C
"Baby, I can't always be beside you
    F                             C           E
But everything you'd need, I will provide you
    Am                                F   
And if you'd feel the world outside denies you
       Am                            F                        E
I will fight away the loneliness and emptiness that bind you
                            F            E
From this world, I'll never hide you
                            F              G
'Til the day my arms you'll slide through, baby boy

C                                    G     F
One of these days the world is gonna find you
               G       C
And take you away from me
                     G       F
The lights are gonna blind you
               G    C
Gonna make you complete
                        E
A girl is gonna hurt you
                         Am  G    F
A woman's gonna set your heart on fire
     Am  G    F
Your heart on fire

F   Am   G F C   F   Am   Am G C

    F                            C         E
And even when you've left me far behind you
Am             G             F
No one's gonna love you like I do"
