Lately, Kate has been attempting to act as a mediator between the Sussexes and the Royal Family. However, Meghan is refusing to accept any help and is convinced that Kate is interfering in her marriage.
From OK! Magazine:
Kate Middleton and Meghan Markle's feud might've reached its peak! Meghan and Prince Harry's relationship with the crown was severed after they abandoned their positions as senior-level royals, but Harry's loved ones credit his wife for his change in lifestyle.
A royal insider claimed the Princess of Wales was disappointed in the monarchy's response to Harry's behavior. "Kate feels terrible that the royals and Harry are at this current impasse with so little contact between them," the source explained. "She blames Meghan for it almost entirely and the longer it goes on the more it upsets and frustrates her."
"Kate's let it be known to the Palace aides who still speak to the Sussexes that she thinks it's an extremely poor show the way Harry's being treated," they added.
Kate's influence on the famous brood angered the Suits star. "But Meghan is furious and thinks Kate has no right getting involved in her marriage," the anonymous friend admitted. "She would never dream of interfering between her and William."
Kate's attempt at mediating things between the fab four became the focal point of Valentine Low's book Courtiers.
"She was often the peacemaker, or tried to be the peacemaker, with Harry," Low said.
It's unfortunate that Kate's attempts to bridge the gap between the two families are being met with such resistance. But it's not really surprising; after all, the more separated Harry is from his family, the more control Meghan still has.
