Welcome to the thread. Have a mushy.Well - as they reach the end of their first year outside the RF, Harry will no doubt be recalling all the family time he used to have at Sandringham as Christmas approaches. He may believe that Meghan had good reason to cut her dad out of her life - all he knows is what she's told him, after all - but now that he has spent many, many months with her (and Archie) in a new country, in a new house, cut off from all his friends and family, I can't see that Harry WOULDN'T be thinking that maybe Meghan was the problem - not everyone else, as she constantly claims. I believe that it must have crossed his mind, anyway.
I think his thought processes are slow. She's far more intelligent than he is. Having gone to live in the USA with Meghan, and having been exposed to her (and almost nobody else) for months and months and months, I believe that he's starting to question what's been happening. He never says anything on social media - she does all of that, for the pair of them.
At this time of year, before most of the world was locked down, people value their families enormously and want to spend time with them.
Harry must have worked out by now that Meghan doesn't like his family. She, on the other hand, has deliberately chosen not to associate herself with her family. I believe that Harry has to be looking at his wife and wondering why.
WRT the miscarriage - I am sure there wasn't one. No miscarriage ever starts with a pain so sharp that you drop to the floor (singing anything) so that is just nonsense. Miscarriages start with bleeding. The pain sometimes doesn't start for days. If she was really in enough pain to have dropped to the floor, she would have dropped Archie as well, and been entirely incapable of singing.
Harry MUST KNOW that the miscarriage story is a fake. Even if she did have a miscarriage, it couldn't have happened as she described it. He will have read what she wrote about it and shaken his head, realising that his wife was lying.
To be honest I think you are assuming hazza has moderate intelligence. Big mistake. He is thick as tit and I strongly suspect has some sort of ism on top of that (sorry guys). An attitude like his doesn't just come from a spoiled upbringing. As we say in these parts "There's a wee want in him". Always was and Di knew it and favoured him to try to allow for it. He had to repeat a year at his prep school and we all know of the Eton cheatin' fiasco to get him into Sandhurst. Apparently he has not got his full helicopter licence either and was only ever the co pilot when in service. This has been said a lot on military forums. Wills has his full licence and has flown the search and rescue ambulance helicopter in the UK ... again something hazza will no doubt have taken as yet another personal insult. He has an utterly tit personality, even allowing for an ism, and smeggy has nourished that paranoia and deep rooted resentment and jealousy of William to keep him away from his birth family.
Basically what I'm getting at is that what most people would catch on to (regarding bad behaviour in a spouse) he will take much longer to cotton on to. Plus when the penny starts to drop he'll be in denial and try to cover for her because God forbid he admits making another bad decision. He'll bluff it out for a few years yet.
