Understanding Kate and Meghan's rocky relationship

Ever since Meghan Markle tied the knot with Prince Harry, there has been a whirlwind of rumours plastered across tabloid magazines and online articles. And one topic has been consistent: Meghan's rocky relationship with the Duchess of Cambridge.

Many assumed that Kate would seamlessly take on the role of Meghan's mentor since she's had years of royal experience over her new sister-in-law. Most of us also hoped William, Harry, and their two wives would become a tight-knit fab four. Both of these things didn't happen.

One book, Royals at War by Dylan Howard and Andy Tillett, unveils how Kate and Meghan's relationship got off to a shaky start when Harry first introduced his new girlfriend to his brother and sister-in-law.

The book shares how Kate was worried that the relationship was moving too fast. She even pulled Harry aside to express her thoughts:

She gently reminded him that he was dating someone with a completely different life, past, and career and it would take time, care and attention for them to integrate.

And then William was longing to meet her and so was Catherine. So, you know, being our neighbours we managed to get that in a couple of - well quite a few times now and Catherine has been absolutely...

This is where Meghan swoops in and says, 'She's been wonderful'. On the outside, it looked like everything was fine. Still, the Duchess of Cambridge and the Duchess of Sussex have continued to have a rocky relationship. But their lack of connection may be due to Harry and William's rift.
