I think it's best a remarriage doesn't happen at all. When Fergie was an "HRH" she was all over hte place making a huge mess of herself, but also dragging the RF along as well. Without the "HRH," she can only ruin herself and she is actually under more constraints because she has to be somewhat careful because she needs to make a living. She doesn't have HM to fall back on to pay her debts, she has to do it herself. The courtiers dont' have to clean up her messes, they don't have to worry about her image, and Andrew isn't going ot run the risk of a laughingstock. She's done so much damage and I think that at some point, in the future, she's going to do something that will be even worse.
Her scandals are getting worse and worse and worse and the quotes from her new book shows she's comepletely slipping out of reality and I think the next scandal will be historical in proportion. He might be unable to make nice friends if he has his ex hanging around all the time. Successful women who would make good consorts do not want a mooching ex hanging around where they are living.
