Meghan Markle and Prince Harry are rumored to not be as suited with each other as Prince William and Kate Middleton are.

Jo Hemmings, a dating expert, told Yahoo’s “The Royal Box” that one of the biggest differences between the royal couples has to do with passion. Prince Harry and Markle have a passion that is not normally seen by the public when it comes to Prince William and Middleton.

However, their public displays of passion could suggest that they are not as suited as the Duke and Duchess of Cambridge who has been effortless with showing their love for each other and staying together since 2011.

“You really sense that these two have a great, intimate relationship. They’re not necessarily as obviously well suited as Kate and William, as she is a fairly dominant woman,” she said.

Royal historian Kate Williams interrupted Hemmings to ask what she meant by dominant. The dating expert said that Markle has made huge changes in Prince Harry’s life.

Hemmings also went on to say that the public has always viewed Prince Harry as the really vulnerable one between him and Prince William. This is the reason why royal fans have always felt the need to protect him and they have also hoped that he could find a strong wife.

“It was quite speedy, between meeting, getting married and to have a baby, but there is a real sense of passion and lust. We want to protect Harry, we’ve always wanted to protect Harry… He’s felt like the really vulnerable one to us and along comes a strong woman for him, a strong wife, but she’s quite dominant,” Hemmings said.

Prince Harry and Markle have been married since May 19, 2018, and their relationship has been plagued with criticisms. Most recently, there are reports that they will soon separate from Prince William and Middleton as the latter couple prepare for Prince William’s new position as King.
