Without including at least some of the Markle drama the story will be incomplete, even from a very favourable H&M perspective. Whatever one thinks of the various members of the BRF's role in this, her family's contributions to the insane atmosphere surrounding the couple before and after their marriage both publicly and privately is something that has to be hugely impactful.
If Harry has really been desperate to walk for years, he should have done so before the wedding, that would have been a good time for a clean break. If they had been planning this for over a year say since the Australia tour then they shouldn't have rushed out a disasterous list of demands that were unviable and B) not accepted so many important patronages and other things whilst planning an escape.
they would say I suppose taht they didn't "plan an escape" but that they were driven to look for a way out because they were so unhappy.. and that has cropped up in the year or so after the wedding. Depends on what you believe.. did they plan an escape from earlry on, soon after or even before the wedding..? or did they both get vrery depressed over the past months, roughly since Meghan was some months pregnant and they had Archie... and they just "had to get out" . we shall see what's said when the book comes out...
