@Gardeningtime (and others!)
Thank you for the really thoughtful and nuanced posts here - how refreshing, instead of the usual slanging match - oh, and the reduction to 'It's racism', too.
Looking into my crystal ball...I really don't see any chance for reconciliation if that means turning the clock back and going back to how things were just after the Sussex wedding. H & M's behaviour has been beyond appalling and they spitefully attacked and defamed so many people that a 'sorry - can we come back?' just isn't going to work.
I suspect the marriage will end in the near future, but whether H & M will separate officially is another matter. Someone posted on here recently to point out that Harry will benefit from another huge financial legacy at the age of 40, so Meghan (however sick of him she might be on a personal level) will probably hang around until then. Also she needs to consider how viable her brand would be without him. In shallow Hollywood terms she's past her sell-by date as an actress, surely. And the Sussex brand itself is so tainted now - it's almost a curse to be connected with it!
I hate the fact that those children are cut off from their relations, and for their sake only I hope there'll be an opportunity for them to come to the UK and meet their cousins and other relations. But I don't know how that could really happen - Catherine will never want any kind of relationship with Meghan and who can blame her? I think Charles will go soft over Harry - and again, I understand that up to a point - but I hope he doesn't extend an olive branch to Meghan. Harry's mantra is 'What M wants, M gets', so I don't see any chance for a real reconciliation between father and son until H & M break up, when no doubt the Crown will end up paying a whacking settlement to Meghan...in a sort of blackmail arrangement, I imagine - because I'm sure she'll need paying off if she's not to write some very nasty memoirs.
So I see H coming back, tail between legs, at some point and Charles giving him a little house to live in quietly on a modest allowance. I don' t want to see him return to being a royal and having official duties - he's shown us what a vain, whiney twit he is and few people could take him seriously any more. I don't see the 2 of them returning to the royal fold because, at the first sniff of any kind of problem or perceived slight etc, they'd have gathered enough material to blackmail the RF again. At the moment they've run out of that precious resource, so they're keen to return and garner some more.
Meghan will never fit into royal life. Counter-intuitively it needs an absolute absence of ego - you have to do what you're told to do, wear what you're told to wear and keep your mouth shut about your personal opinions. You are there to serve, not to spout your views or to make events etc about you personally. I just don't think she ever 'got' that, and never could.
