I mean, does it really matter if William is shagging about all over the place? It's not a big deal in those circles. I would be gobsmacked if the Wales's divorced. Kate has basically subsumed her entire life into being Williams wife and William knows the stability of the Monarchy is at stake if there's another scandal. He must also realise thst Kate is the perfect Royal wife. The only reason we know about the other affairs was because of the divorces. Right up to the end of Charles and Diana's marriage the rumours were denied by the Palace and often the press until they themselves decided to speak out, then all the stuff that the press had been hiding for years came tumbling out
We're in a different era now. The only reason Charles and Diana's divorce was so shocking is because divorce was not acceptable in that era.
Now, 3 out of 4 children of the Queen got divorced. Anne's son got divorced. And many royals around Europe also got divorced.
Close to 50% of marriage in the UK end in divorce. Looking at my own family, my parents and all of their siblings are divorced. It is very normalized nowadays. A divorce will not rock the monarchy especially if the split is amicable.
Obviously, none of us know the truth so there is no need to speculate but I wish them the best and happiness.
If it's not true, I feel bad for them because this seems to be a rumour that will never truly go away and for the children too, who knows what they heard. Children can be mean and repeat what they've heard from their parents. William, himself, used to be teased a lot at Eton during the War of the Waleses.
