Splitting the Royal Foundation, though, might not be enough to ease the tension. The issue is very simple. Harry and Meghan appear to be attempting to forge a path that isn't proper to their role.
Meghan was an actress who was working very hard to become a star when she met Harry. The problem is, she took a part in a lifelong drama of which she can never be the leading lady. She chose that, and kudos to her. If she loved Harry, I am glad she didn't let anything stand in her way. People and relationships are the most important things in life. Meghan didn't have to marry into the Firm.
Chelsy Davy, who clearly loved Harry, couldn't take the plunge. She didn't want to live her life in a fishbowl, so she walked away. Meghan's problem is the opposite. She is very comfortable with the fishbowl; in fact, she has actively sought it for the entirety of her adult life. Her problem is on the other end of the spectrum, and that is she can't advance beyond the role she has chosen.
As I mentioned in my earlier post, a global Sussex brand isn't what the monarchy is about. There is no global York brand, or global Princess Anne brand. The royals who aren't in direct line play supporting roles...forever. Meghan is the Duchess of Sussex, her spouse is a popular prince, but his position in the BRF will drop, and his star will inevitably fade as the years roll on. See, e.g. Prince Andrew.
The tug-of-war between the Cambridges and the Sussexes comes down to a power struggle--the outcome of which has already been decided: William and Kate are the winners. But, how Meghan and Harry finish has yet to be determined.
