I know this girl, she's always on my mind 
She lives in her world and I live in mine 
I should forget about her and I've tried 
Lord knows I've tried 
But I want to know her, and here's the other side 

I've got someone waiting for me every night 
She's the only one I've ever loved 
And it's been that way for the longest time 
She's the one that makes my world go right 
And it tears me in two because I know where I'll be tonight 

I think she knows it 
I think she knows 

Two different worlds, two different worlds 
One that belongs to me, one could be wrong for me 
Two different worlds, two different worlds 
Oh, two different worlds 

Is she that different or is it the thrill of someone new 
Strung out on her, I need her love 
I need it bad, and I know, I know it's true 
I'm the one that lies awake alone 
I know, she's the one that makes me stray from home 

And I know it 
Yeah, I know it 

Two different worlds, two different worlds 
One that I may regret, one that I can't forget 
Two different worlds, two different worlds 
Oh, always two different worlds 

No, I can't explain this emptiness 
No, I know I can't go on like this 
Two different worlds, two different worlds 

Two different worlds 
I live in two different worlds 
One that I may regret, one that I won't forget 
Two different worlds 
But I can't live in both, I know 
One world I must let go
