(Boy, you're so hard to believe!) 
Yeaaah, yeaaah
Ooooh, not, no, no
(Boy, you're so hard to believe!)
Huh! 

Just a friend 
That's all I've ever been to you 
Oh, just a girl 
Who wants to be the center of your world 

But I ain't got much to offer 
But my heart and soul 
And I guess that's not enough 
For you to notice me 
I'm just a girl 
And I guess that's all I'll ever be to you 
To you 

I try to smile when I see other girls 
With you
Acting like everything is O.K. 
But, oooh 
You don't know how it feels 
To be so in love 
With someone who doesn't even know
My secret love 

In my dreams 
I see us both together constantly 
Why can't you see 
This love that's here for you inside of me? 
(Oooh oooh, yeah)

What do I have to do 
For you to notice this? 
You look at her with love, 
With me it's just friendship 
I'm just your girl 
And I guess that's all I'll ever be to you 
To you 

I try to smile when I see other girls 
With you (with you) 
Acting like everything is O.K. 
But, oooh 
You don't know how it feels 
To be so in love 
With someone who doesn't even know
My secret love (my secret love)

What do you see in her 
You don't see in me? 
(Don't see in me) 
Boy you're so hard to believe
(Boy you're so hard to believe)
Why do you show her love? 
But there's none for me (oooh)
Boy you don't make sense to me 

It's 'cause I don't have much to offer 
But my heart and soul 
And I guess that's not enough 
For you to notice me 
I'm just your girl 
And I guess that's all I'll ever be to you 
To you, you, yoooou, oooh 

I try to smile when I see other girls 
With you 
Acting like everything (oooh) is O.K. (everything ain't O.K.)
But, oooh 
You don't know how it feels 
To be so in love (so in love with you, baby)
With someone who doesn't even know (oooh yeah)
My secret love (my secret love, my secret love, my secret love)

Oooh No,
Oooooh 
Na na na na na na na na 
Oooh

Boy you're so hard to believe
