It is obvious that they both care very deeply about each other, despite all the ups and downs. I'm sure their daughters are better people, because of the devotion of their parents. I recall hearing Sarah interviewd on an American TV programme, and in response to the question of whether she and Andrew would remarry she said something like "they (meaning the Royal Family) wouldn't allow me back". They both seem happy with things as they are at the moment, and Sarah is living the Duchess lifestyle (i.e. holidays, charity events, social functions) in all but name!
