Meghan obviously has some sort of personality disorder going on reported behaviour. She was accusing of bullying staff and having a fit over a tiara literally 5 minutes in from becoming a member of the RF.
She was a minor actress in a cable TV series, obviously not used to the trappings of royalty, and most people in her position would have been a bit over awed and respectful of being part of a world famous, centuries old institution, not barking orders at staff, messaging them at 5am, making them cry, throwing cups of tea or demanding particular tiaras!
Certainly not dictating to her brand new SIL (a future Queen) on what her toddler daughter wore on her legs with her bridesmaid dress, or degrading her to 'pregnancy hormones', and telling the world that she made her cry (stopping short of saying what she actually did though) and wasn't keen on letting her borrow her lip gloss, although she did. I mean, how spectacularly petty!
I see there were reported issues with staff turnover in the US as well.
Meghan was a member of the RF for less than 3 years when they did the Oprah interview after they ran off to Canada in a huff after being told they had to abide by RF protocols. She seems to have thought she could dictate what role she would have and was so full of self importance that I think she thought SHE would be the one who would be the most important and popular member of the RF.
Aren't delusions of grandeur a classic sign of narcissism?
There was no way someone like her would play second fiddle to Kate, but why not though, Kate had been part of the family for much longer, was to be the future Queen and rightly had much more of a visible role. Most people would have understood that and probably been a bit relieved that they wouldn't have such a visible role but not if you want all the attention on you!
The running off after not getting her own way was classic narcissistic rage as was all the mud slinging about the RF afterwards.
I firmly believe the books, including Harry's, and the Netflix series was all down to her. I really don't think Harry has the capacity to come up with all that.
I also think she set her father up because she didn't want him at the wedding, or be involved with Harry and the RF because she thought he was beneath them, and her in her new royal life.
I think Harry is not a nice person either, and is just as jealous of William as Meghan is of Catherine, and was a willing participant in trying to destroy the RF before William becomes King. He definitely wouldn't have had the ability for the calculated deceitfulness and strategic tactics to do it without her though.
