Men who marry into the royal family are subservient , conformist husbands
They are, Annie. Look at Prince Philip who had to give up his career.
Whether men or women, they have to try and fit in. It's reported that Meghan was given every opportunity to learn about Royal protocol, including one of the Queen's own assistants to give her advice, but that she didn't want to take it, and she thought she could change things to suit herself, never mind 1,000 years of history. (her "Hit the ground running" comment).
I've always thought that Annie's comment was right in that Meghan thought she would be "Queen Bee" and didn't like it when she wasn't. She was jealous of Kate's status.
