I remember thinking the same. In fact my own relationship was on the rocks at the time of their wedding and I remember feeling a pang, and thinking how bloody proud her parents looked as they stood on the balcony with the Queen and their newly married-into-royalty daughter.
That seems like an eon ago in terms of my attitude.
Today I would absolutely NOT be delighted at the thought of my daughter marrying into this deeply dysfunctional family.
Catherine was too good for them, and I would argue, is what is saving them. If there were scandals about Catherine, it would all be over in my opinion.
The Middletons (mother especially) were painted as ambitious social ladder climbers by the press, who pushed their daughter onto William, but I have no idea how true it was. Seemed like nasty tabloid gossip at the time. But in hindsight, with the gift of maturity, all the Diana stuff had come out. Fergie was out the family. Diana was dead, pursued by paparazzi. Prior to that there was the Margaret scandals and various other scandals in-between. Would I have wanted my daughter marrying into that? No. I would have pleaded with her to think twice and sent her on a very long holiday outside the UK during the temporary breakup in the hopes she'd move on.
Catherine today could have been a very well to do upper MC mum, living quietly in anonymity. Going anywhere she wants without scrutiny. Now, she cannot even be ill without the press demanding to know what's going on. Called Waity Katy for years and work shy. The nasty revelations by the Sussexes. Now Lownie hinting at financial excesses. I too, wonder whether her parents are happy about it all now. You hardly hear about Pippa, who seems to have a happy ordinary life.
