A number of years ago my husband and I were invited to his bosses wedding. This boss had been married before, to a woman who was loony, had two children, became unhappy, had an affair, divorced the loony wife and prepared to marry the woman he had an affair with.
I found it insulting that these two people, who had behaved so badly, had the collosal nerve to ask people to stand up and support and celebrate their union. I refused to attend.
Go get married quietly if you think you need to be married. But don't throw your bad behavior in my face and ask me to support it. That is what has happened with Charles and Camilla. We're supposed to put aside the fact that they have been pigs and now support their "romance". Barf.
