I think Harry convinced the rest of the RF that marrying someone he hadn't known that long was a good idea, and probably ignored their urge to be cautious. PC could hardly say no after not being allowed to marry the woman of his dreams.
I think Harry fell for her and also saw in her an opportunity for them to both create a niche role together alongside his brother and Kate. They might not end up king and queen but could have 'the popular vote' so to speak by being the people's prince of hearts, like his mother. He really wanted to be popular and for it to continue, maybe not as much as Meghan wanted it, and he saw this as the way to do it.
Problem was Meghan is very American which is all very well and good but her style didn't suit the UK public. We didn't want to be lectured to, which Harry got in on too, or put her on a pedestal. I think we like the RF to be low key, not gussy, attention seeking etc. By and large most ignore them. What we don't want is more scandal and to learn of their excesses. The whole point of them surely is they should be beyond reproach at the very least, why have them if they're not, if they're as fallible as the rest of us. They've turned into a soap of late.
The other problem was her manner - the bits of the engagement interview I saw were nauseating. She thinks though that's how you 'act' adoring and in love, like a Hallmark romance. Same with the mannerisms, the photo ops, the body language. It turned people off - we didn't think her genuine. She came over as acting and people took against her and them when the lecturing came on top of it.
The other big problem was what she did to her dad. She'd praised him a number of times on the Tig, how wonderful he was. He didn't deserve to be cut out like that. Harry never even bloody met him! That is shocking for the RF, let alone anyone else. I don't think he was even coming. The week before the wedding he didn't have a suit. He's given interviews yes but because he's desperate and in pain.
Another things was the wedding. I don't have a big family. I and most others would say can we please have a quiet low-key wedding so that is not highlighted. Even though he's the prince there was no reason for the big do they had with her in a white dress being walked down the aisle by her father in law! She could not see how bad that looked. She thought perhaps it would make people feel sorry for her. I thought the optics, which she is all too aware of but continually got wrong, were off - bad move.
I think her mother is lovely. If Meghan had come over more like her mother she would have had an easier ride. I also think PC in particular welcomed her as did the queen by taking her on that appointment - giving her acceptance in public. I think they did it for Harry's sake of course to give it every opportunity to work as they knew the fallout would be terrible.
Problem is now Harry invested so much in this working he must be gutted to find we don't all love her and think he's turned into a pompous, no-it-all arse. Meghan knows she won't crack the UK market so gave up quickly - why? Because I don't think she truly loves Harry, but that he was an opportunity that went tits up basically so she cut her losses.
Of course, they'll play the victims - of racism, sexism, this'ism, that'ism. I doubt they'll split right now. She hasn't achieved what I think is her aim - global standing and lots of money. She needs the title etc and no more scandal for a bit. Let's see what happens.
I hope anyone thinking of doing business with her and him see what they are truly like and think twice. Harry has to go along with it or he loses Archie. Poor kid. Perhaps he'll come to the UK for boarding school.
One thing I always wondered was if they took Frogmore as it is near Heathrow so convenient to slip in and out of the UK without people knowing if they use private jet while if they'd stayed at KP they might have been seen coming and going. I always wondered if it was a reason as they planned to not be in the UK that much ages ago.
