Cover art for The Way You Want It lyrics by Keane

I see it more like this guy wanted a girl for so long, and by the time he has gotten over her, she wants him. Hence, "even though you've waited so long to see the day when she will turn to you again" and "so long, my friend is what you say".

Maybe they broke up, and the guy still wants her, and THEN as soon as she realizes she wants him too, he changes his mind...?...sorry, this made a lot more sense in my head, haha.
