Looking through this thread for the first time - some things stuck with me....
b) I was a little shocked that Harry would reveal intimate things about Meghan in his book (Spare) and in interviews. And further shocked that Meghan didn't know he would reveal such personal stuff about her. If true, as i am sure it is, then it seems in keeping with a). If true I can well understand why Meghan might be upset and angry with Harry. ....
I'm 99.9% sure that Meghan's hand was all over the Spare book, just like it was with that first ridiculous book called "Finding Freedom" where she claimed she had nothing to do with it, only to be found out that she was very much
involved and gave info about their private life.
She basically committed perjury in court, but got away with it when she claimed she forgot about it.
I don't think Harry does anything without Meghan's approval, she seems to be his handler. ...
What you say makes sense. I change my opinion (bit in bold) to "Surely it cannot be true, Meghan must have seen the pre-published book and given it her approval". Hence the noise (hearsay) that Meghan was shocked and angry by the intimate revelations of Harry's new book and his interviews on it cannot be true. If there was anger and disappointment it must have been for another reason.
