I agree with some comments on here. It's a song about a love affair between 2 people who both are married or are in other serious relationships, they live away from each other, occasionally ring up each other (from Paris to New York), meet somewhere in hotels. They miss each other when they are away from each other and people who want them to fall down are the ones who maybe see how strong and breathtaking their relationship is and envy it.
