I think this has been the plan of the narcissistic, money grabbing, praying mantis from the start - and Harry was an absolute idiot to fall for her act. He was warned and didn’t listen and now, as well as cutting off her own family, she has alienated Harry from his family and friends.
The royal family need to remove their titles, funding, security, Frogmore Cottage etc, with immediate effect. Do not allow them to have this part-time royal status with benefits that they want - cut the ungrateful wretches adrift before they do any more damage. IMO.
