The tension between Harry Meghan, Duke of Sussex, and William Kate, Duke of Cambridge, has lasted for 4 years, and the reason for the conflict is that William dissuaded Harry from proposing to Meghan in a hurry, but in addition to his concern for his brother, William's dissuasion seems to be related to his own lack of favor with Meghan.

This year, Harry Meghan again declined an invitation to return to the British royal family to celebrate Christmas, meaning Harry will once again be absent from the Christmas traditions he and Prince William have been going on for years.
For years, both william and harry brothers hosted a charity football match at Castle Rising in Norfolk after Christmas, with the participation of both princes and royal staff.
Before 2014, the brothers would join different teams to play against each other, and in 2015, the two brothers wore the same jersey for the first time, and the powerful duo led the team to the final victory in the arena.
It is worth mentioning that in the final final, neither of the brothers made a shot, but gave all the opportunities to a local 13-year-old boy in the team, and then stopped to watch him shoot, which made the two win the respect of everyone present.
In interviews in the past, the brothers have talked about their unique Christmas tradition and stressed that the annual ball game is the most unique and strong bond between the two of them, which is related to the fact that both princes have loved football since childhood.
But in 2016, Harry missed the game, and after celebrating Christmas at Sandringham Manor, the prince rushed to Los Angeles to meet his girlfriend Meghan, who had only been friends for a few months at the time, and William did not participate in that year's game without Harry's company.
In 2017, Harry was completely busy with his engagement to Meghan, a tradition that seems to have been forgotten.
Is William not optimistic about Megan because Megan caused him to be snubbed by his brother? Of course not, william as the elder brother could not reject Megan for such an egoistic reason, and what really upset him was that Harry was "too involved" in the relationship to completely "lose his mind".
Not only did he not have the time to play the game on his own, William noticed that his brother had almost no life of his own since he fell in love with Megan, and that Harry had pushed almost everything else except the necessary royal duties, running to Megan whenever he had time, and that both himself and Kate and Harry's former friends had been thrown aside by him.
In addition, Harry also made a series of "irrational decisions" for Meghan without his brother and other royals, so that Harry's friends asked Harry to discuss any decisions related to Meghan in the future, but Harry was also provoked by this suggestion and directly broke off relations with his friends, and the other party helplessly found William, and Prince William, who learned of all this, was once again more worried about Harry Megan's love affair.
In 2017, Prince Harry, who had only been in a relationship for one year, told his brother that he was proposing to Meghan, and Prince William, who thought that Harry had completely "lost his mind", dissuaded him and broke out with Harry, in his opinion, Meghan was definitely not the person who was suitable for Harry's future royal role, and it turned out that William's view at that time was not wrong.
