We've loved Prince William and Kate Middleton as a couple ever since being first introduced to the royal pair many moons ago. The world has adored watching them blossom from first loves to an adorable family of five.
Despite the fact that they appear to be one of the strongest couples in the public eye, royal biographer Andrew Morton claims that William "treated Kate like a servant" when they first started dating in 2003. In his 2011 biography, William & Catherine: Their Story, Morton alleges that William was "obstinate and strong-willed."
"William could be an overwhelming presence at times, Kate felt taken for granted – treated like a servant rather than a girlfriend."
He added, "He expected Kate to run after him and the longer they knew each other, the more he seemed to keep her on a tight leash."
The Duke and Duchess dated for four years before they briefly split in 2007, which William addressed in their engagement video in 2010.
"We were both very young," the prince said. "It was at university, we were sort of both finding ourselves as such and being different characters and stuff, it was very much trying to find our own way and we were growing up."
"It was just sort of a bit of space and a bit of things like that, and it worked out for the better."
