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
