I'm not really on board with that narrative.
Pre-M he seemed in a pretty good place especially with Invictus in having a real purpose and direction of his own (but I concede looks can be deceiving).
Yes, I'm sure he wanted a relationship but I just can't see any evidence that he was as unhappy as he claims he was.
It will undoubtedly upset the Sussex Squad but I do feel (as pleased as I was for them both in the beginning) that their relationship has not brought out the best in each other (so far). That said I don't wish either of them ill will. I'd much rather they found their niche and were successful in it for the sake of their children, themselves and the constant slow crash I seem to be unable to keep watching to my own chagrin.
Personally I see them both as people who had a void to fill and thought each other would be the perfect fit - but actually they both got round pegs for a square hole.
H wanted what his brother had with C and was thrilled to find someone adept at handling the media, wasn't phased by joining the firm and was of course very beautiful/ charming/intelligent.
M found someone who could give her the status and platform she had coveted her whole life who was affable and loving/protective.
The problem was that the life M thought she was signing up to wasn't what she got.
She misunderstood the difference between royalty and celebrity and in doing so didn't realise you can't have a foot in both camps on both sides of the Atlantic.
Didn't need "help" because she understood PR/Branding and how to manage the public. Possibly genuinely thought she could teach the RF a thing or two in this regard.
So reality strikes and yes she is unhappy. It's not like being a celebrity at all. No you can't get designer freebies. No you don't just get to pick a choose your engagements - you do the cold wet meet and great in Fife as well as the film premieres. You don't get to choose your patronages. Most of all you don't get to have flash baby showers in the US with your new A list besties and the vision you had of a life split between the UK and US being toast of the town in both evaporates.
In addition you get shitty press over dumb rules over nail varnish and tights and some thinly veiled racist copy and some overtly racist attacks on SM.
Then you realise your husband didn't prepare you for any of this - as belatedly so does he.
So do you start to blame each other or do you make a decision to blame everyone/anyone else and find a way to make the life you envisioned rather than the one you ended up with?
So that leads us to the Megixt manifesto of half in, half out that was roundly rebutted and the whole "it's not us, it's them" mentality was further cemented because admitting you were unhappy due to your own misconceptions/rash choices/failure to test the waters/take things slowly/take advice etc simply wasn't an option.
They absolutely could have chosen a different path in having independence and maintaining a positive relationship with the RF. However that wasn't compatible with their narrative of "you made us leave".
It's a mindset they still haven't broken away from regardless of any opportunity to reflect on the negative consequences (not least to themselves) of their behaviour imho.
