It does make sense that it could be about her cheating on him, although I think it's just about a sad, dying relationship. I don't think they'd sing the middle verse & chorus together if it were about cheating.. They both seem to mutually agree that they're 'turning into dust' and the relationship's just not what it used to be.

'The truth hurts' because they've been trying to tell themselves they're still deeply in love, when in reality they aren't.

One of the saddest songs I've heard in a long time, very moving and very relatable for a lot of people :( Thumbs up to James Morrison.
