About an ill-fated non-romance that was never going to happen

I was so damned comfortable you from the day we met, So easy to reach out for you, so easy to forget, I'm not your lover, I suppose I'll never be... It's hard to stop the dreamer's dream, I can't forget this fantasy, (Chorus) Whooa, I was a victim of desire Whooa, better keep away from you. Whooa, got so close I could feel the fire, Whooa, and there's nothing I could do. This feeling once was buried deep inside of me, A Pandora's Box I thought I'd sealed so well and lost the key, Now that box is open but I can't let things run wild, How can I be a strongman when I'm just a helpless child, (Chorus) I need to find some self control to keep away from you, But it's the pull of gravity, you must feel it to, I wandered right up to the edge, but I must walk away, I belong to someone else, can't save you for a rainy day, (chorus)
