I think all of this essentially boils down to William being right.
If it's true that he suggested that things were moving too fast, he was 100% correct.
In any situation, this has been a very fast moving relationship/engagement/wedding/pregnancy/baby.
For anyone entering the Royal family, it would have been a bit of a shock. There is so much protocol and etiquette to learn, and then there's the rank and file, and the duties, and the orders of the garter etc etc etc.
For all of their own mistakes W&K were together for a number of years before they got married. They spent three relatively quiet years together at university, generally ignored by the press.
Then Kate spent years in the public eye, gently being introduced into the Royal Family, being introduced to his friendship circle.
She put up with a LOT of press attention and did it exactly as the Royal Family wanted. She proved herself able to deal with the press attention and the requirements of being the wife of a future King.
I appreciate that there was the break up and the rumours that William was looking for someone else, but the reality is that being the wife of a future King involves much more than love.
You can love completely the wrong person, we've all been there. It takes time to really learn who a person is, and how they behave in different situations. This is especially important in the public eye.
Then once married W&K took it slow. He isn't the heir to the throne yet, so they went off to Wales where he could have a normal job and they could have a few years of normal married life.
It was only really when she was pregnant with George that they began moving back towards London, and have only really been resident at Kensington Palace when George needed to go to school.
I think that was a very savvy move on the part of the Royal Family. W&K were barely mentioned in the press outside of their official duties, which there weren't many of.
I think Harry was every bit as keen as Meghan to get down the aisle, and possibly more so.
He was openly keen to get married and start a family. He had had two girlfriends subjected to the media excitement; both of whom had said "no thanks" and married someone with as much money but without the trappings of royal duty.
He did not want Meghan exposed to that, particularly before they got married. In case she ran. I doubt there are many people in Harry's social circle who haven't already been married off with children; so his choices were not exactly booming.
Hence the quick relationship and engagement.
The Royal Family seem to have tried to slow it down. Apparently the Queen suggested that Meghan not receive a title, so that she could continue acting. That was refused, as was the offer of a place in Wales so they could have some privacy for the beginning of their marriage.
They wanted to "hit the ground running"... and they did. But with that comes the media, and it quickly became out of control.
When W&K did their few engagements a year, I'm certain a lot of mistakes were made. Kate certainly didn't do much speaking in the early days, that came as she built confidence and learned the ropes.
The Royal Family is not celebrity; and I think Meghan and Harry wanted to match up to W&K asap and be The Fab Four.
The royal family have gone too far the other way. They didn't want to be seen to choose brides for William and Harry, given the rubbish job they did with Charles and Diana (and potentially Andrew and Anne given neither of their marriages lasted).
Camilla, in hindsight, was actually a pretty good choice. She was from the right social circle, had an idea of what was expected, and seemed prepared to do it. Until it was decided she was not appropriate.
I'd guess that they wouldn't want Harry, who seems to be harbouring resentment about Diana's marriage, to think they were trying to control who he married, so they let him get on with it - which has proven to be a disaster.
How on earth can a marriage survive this? Even if Meghan had the acting ability to win an Oscar (I have no idea - not seen Suits) - then she's rapidly losing time to get on with it. Corona Virus has put paid to that.
And if she plans on having another child, that will put her out for a further amount of time while she is pregnant and recovers.
I cannot see how they can possibly be financially independent by December. Unless they have hundreds of offers in the bag, which are acceptable to them, they surely won't want to relinquish the purse strings.
Harry will be between a rock and a hard place; unless they are in such a bad position, that Meghan is willing to capitulate.
Then what? By that time the media will have spat them out, and the public opinion will be in the gutter.
They've pissed Canada off with the midnight flit. They could have agreed to do 6 months a year there, in the commonwealth roles, and 6 months a year in the UK doing the trooping of the colour etc.
I suspect there could be a way back, but I'm not sure Meghan can cope with it.
They could come back; and go to Wales as originally suggested (or just back to Frogmore).
They could start again as W&K did. Appear for the major royal events; and start small with small patronages.
Have a lot of time for themselves and Archie, and wait for the dust to settle - which it will, eventually.
Which means the magic question is whether Harry and Meghan are actually compatible. She doesn't appear to be the kind to wander to the pub in a village in Wales and just chill out.
In reality I think Harry has just repeated the cycle his parents were in. Got married without knowing each other, went too fast at being in the headlines, struggled with mental health because of the pressure (I would find it horrendous).
I think that Meghan will end up divorcing him; and he will end up in the UK without Meghan or Archie. She will get quite a bit of money for child support and possibly spousal support (not sure of the rules in California).
It's actually incredibly sad. I wish there was some obvious way for it to work out, but I can't see one.
