I find her half brother, Tom Markle's, letter to PH just before the wedding interesting. I think he is a dreadful character but his opinion on MM at that point in time is interesting:
"Dear Prince Harry,
It's not to late. Meghan Markle is obviously not the right woman for you. As more time passes to your royal wedding, it become very clear that this is the biggest mistake in royal wedding history. I'm confused why you don't see the real Meghan that the whole world now sees Meghan's attempt to act the part of a princess like a below C average Hollywood actress.
What kind of person starts out using her own father until he's bankrupt, then forgets about him in Mexico leaving him broke, over mostly all her debts and when it's time to pay him back, she forgets her own father like she never knew him.
My father will never recover financially from paying Meghan's way, nor emotionally from disavowing him, Meg is showing her true colours.
Its very apparent that her tiny bit of Hollywood fame has gone to her head, changing her into a jaded, shallow, conceited woman that will make a joke of you and the royal family heritage.
Not to mention she doesn't invite her own family and instead invite complete strangers to the wedding - who does that?
You and the Royal Family can put an end to this fake fairytale wedding before its too late."
