Foreigner - Two Different Worlds

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
