The Markle side of her family have shown themselves to be toxic, I totally understand why she cut them off, they are loathsome.
But, it does make you wonder if she was lying all the time she was writing glowingly about her dad, it doesn't make sense, was she doing it for clicks, was it a public finger to Doria who she was maybe estranged from at the time, was it ever a genuine loving father / daughter relationship?.
Why did Harry not meet his future father in law? that has to be one of the biggest red flags in any relationship.
Why did she get her friends to disclose the private letter she sent to him, the letter she hoped he might release to the public, he clearly fell into the trap when he responded, 6 or so months later, to contradict what 'the friends' claimed was in the letter. Meghan used her friends to trap and manipulated her father into releasing extracts of the letter, her father had not said a word about it until then, and then she went to court about it.
Her behaviour towards her father has been as manipulative and loathsome as her family, if not more so, as she had a lot of power at that time.
