The Giulianis had a very publicly miserable and dysfunctional marriage. They were never seen in public together; she publicly dropped his last name and took back her prior husband's last name; she sought out a role in that Talking Cooters play, just when he was starting to gear up his race for the Senate; when he was re-elected in 1997, she made a point of seeking out the media so that she could say she didn't know if she was going to vote for him; etc.
That family was "broken up" long before Rudy took up with a woman who loves him for himself, not for whatever power she could get from him. Did you know that shortly after he was first elected, his wife had a tantrum when he wouldn't give her a "Hillary-like role" in City Hall?
I was fortunate enough to marry a really great guy who treats me better than anyone deserves to be treated - but I have seen friends go through some unbelievably nasty things in their marriages, and from the outside looking in, you would never have known how miserable their lives were. After having seen some of that stuff, I still wish married people could find a way to stay married, but I'm much slower to preach to others on the topic.
I wish the bride, the groom, and the son much happiness. And they can wear whatever they want, as far as I'm concerned. ; )
