I don't think many people would see it that way.
I think most people would see that having a very high profile makes it embarrassing when things go wrong in your marriage - not necessarily personally - but when your partner says that they can't cope with your job or role. I think anyone very famous, such as the US President or the head of a high profile church, would do a lot to avoid looking stupid, or to endure a distraction from their cherished work and role. They would want to know what they needed to do to make things right and acceptable for their miserable or disgruntled spouse.
From what I read on relationship threads on MN, a lot of posters have husbands who are lovely and adore them. It isn't a rarity. I wouldn't assume that people are unhappy.
The difference I think is that, I don't think many spouses would push things as far as saying: "Come out of the role you've been brought up to. Say you won't go along with this plan". There is always a way of gaining privacy within the royal family, or as the wife of an important politician. You just don't do things to be seen. Then the press won't picture you. It's perfectly allowable not to do public duties.
Meghan is fairly unique in being so audacious. Most people on marrying into the Royal Family would just go along with the harmless forms, such as being photographed outside the hospital with your new baby, and would look for a kind of compromise, privately clawing back choices. She pushes things to the max and always publicly. Given the publicity which has always ensued, the publicity seems to be an intrinsic part of why she elects to do things.
It is easy to imagine that Harry was shocked and confused when Meghan wanted this half in/ half out Royal role and to go abroad. Being a little scared of the fall- out and the complete unknown is not quite the same as valuing and adoring your partner. Having to make a rapid decision, he chose the lesser of two evils in turning his back on his role and the firm. To be divorced or separated after a big multimillion pound wedding, and with the commemorative plate hardly off the shelves, would have been a painful and, perhaps, humiliating sadness. He would have feared this outcome. I don't think it was a happy time or a choice very freely given.
