It sounds quite accurate to me. Listen to the song to get it right. basically you have
do long G's and Em's and then strum the G Bm Em or the Em Bm G combos to change from G to
and viceversa. it's really easy if you listen to the song. it's the same chords over and 
til the bridge and after that it starts all over! I play it with no capo

Intro:
G  G Bm Em
Em Em Bm G

G
You dont want me, no
                G Bm Em Em Bm G
You dont need me
G
Like I want you, oh
               G Bm Em Em Bm G
Like I need you

G               G  Bm   Em Em Bm G
And I want you in my life
G               G  Bm    Em  Em Bm G
And I need you in my life

You cant see me, no
Like I see you
I cant have you, no
Like you have me

And I want you in my life
And I need you in my life

C   Em  Am
La La La
C   G   Am
La  La  La
C   Em   Am
La  La   La

C (strum once, stop, then start again with the G G Bm Em etc til the end of the song)

You cant feel me, no
Like I feel you
I cant steal you, no
Like you stole me

And I want you in my life
And I need you in my life

End on G
