This is when Prince William realised he wanted to marry Kate Middleton

Ah, the course of true love never did run smooth, even when you’re actual royalty – but Prince William and Kate Middleton’s story is pretty darn close to the full fairytale.

After meeting at the University of St Andrews, where William studied geography and Kate, art history, the pair dated for nine years before William proposed. And, minor blip with a brief separation in 2007 aside, they seem to have been a picture perfect couple throughout.

However, according to a royal biography from the archives that’s recently come back into the public eye thanks to Marie Claire, there was a particular moment when William became sure that Kate was definitely The One: when they moved to a ‘very romantic’ beachside house in Anglesey, Wales, where William was working for the Air Ambulance service as a search and rescue pilot.

According to Kate: A Biography, a book written in 2013 by Maria Moodythe duo lived in a state of ‘domestic bliss’, with Kate looking after ‘everything related to their home.’

‘[They] had spoken of marriage and they knew it was on the cards but it hadn’t been the right time, until now,’ the author detailed. ‘Unlike other royals before him, William employed no domestic staff and Kate took care of it all…’

‘They both knew what was coming and knew that, although many good things would follow, it would also mean a life of increasing duty and less time to themselves.’

William eventually got down on one knee during a holiday in Kenya in October 2010, using his late mother Diana’s sapphire ring as ‘a way of making sure [she] didn’t miss out on the excitement.’

The couple then tied the knot on 29 April 2011, in a stunning ceremony watched by 23 million people around the world, and their happily ever after didn’t end there. They’ve since welcomed three adorable little ones – Prince George, Princess Charlotte and Prince Louis – and are set to celebrate their eight wedding anniversary next month. Aww!
