I've a feeling this is going to backfire badly on both of them, I think there is no doubt where this vitriol is coming from, a princess who didn't like playing second fiddle and not liking being lower down in the pecking order (read billing) of the Royal Family, so she does the only thing she knows how to do and that's self publicize, it's Harry I feel sorry for he's given up everything to be with his tv show wife, his life will now consist of endless chat shows and tacky hollywood PR stunts, and I reckon she'll keep him around for as long as he's useful, then claim irreconcilable differences and divorce him.
2 years maybe 3 tops
she has a history of moving on......after all
