I think it's Harry who is like Diana not Meghan.
Diana was not academic but had a natural way of interacting and connecting with people.
Like Harry.
Diana was emotionally fragile and easily manipulated by people.
Like Harry.
Diana had naïve romantic notions of love which she tried to fulfill in unrealistic relationships.
Harry thinks he's fulfilling this now but it's in such a naive clichéd way which doesn't feel real or sustainable.
Diana became paranoid and believed the firm were out to get her.
Like Harry.
Diana believed telling her truth would garner sympathy and was manipulated by journos into believing this.
Like Harry.
Diana was a tragic figure.
Which Harry may sadly become.
I don't think this is because of MM I think some tragedy/ drama may have played out whoever he was with, because of him.
It's because of MM it's taking this particular path/ story.
