I agree that it could be an affair. The lyrics fit, '' Do they have to know, about my goodnight girl? '' It could be that they ring or text each other every night to talk and say '' Goodnight'. ' Maybe one of them is in a relationship they can' t end because there are children involved, or the partner needs them emotionally, so they grab whatever time they can get together as it is better than nothing, even though they know they will probably never be able to be together properly.
