To be honest, I see Meghan as his enabler, a partner in crime so to speak, not the lead with him meekly following,
The problem I suspect they have, is Harry doesn’t have anything other than being royal. That was his platform. Meghan does, she has her acting career, which being royal enhanced, boosts her profile, but she has a skill set and a name there. Loosing the royal titles doesn’t really impact her so much as it does harry.
If Harry loses his royal status, which he wished to keep then he’s in a difficult position, what work will he do? Speeches for money and the invictus games ? That will get old fast. He can maybe milk it for a couple of years, but after that he’s a has been that people loose interest in.
I think that’s why they are fighting so hard to stay royal. It’s all he has to offer and they know if he looses everything he is in a difficult position, his only options would be become mr Meghan or go back into the royal fold.
