Harry will feel the emotional distance over time.
To date he has been buoyed up with the excitement of his marriage, birth of his children, escape from UK and RF expectations, lure of exciting and prestigious commercial projects etc - alongside all of the global media attention from his exposes via Oprah, NF, Spare, interviews etc which look to have been validating for him.
This might be enough to sustain his identity and emotional core - but it seems not as he is now reaching out in a delusional and grandiose way publicly to those he hurt (RF) with no insight, empathy or care as to the impact and sustained damage his repeated actions caused and where these people are now emotionally.
I suspect the exclusion, silence and lip service will over a very long time leave him confused and lonely once he realises he is persona non grata. I think to date he believed he held all the power with his relentless missives and noise across the global media. But that’s just short term.
The long term ‘grey rock’ and ‘cold shoulder’ counter offensive is only getting started and will continue for decades as he is cut adrift not just from his family but longterm friends and society in the UK - I suspect it will sting.
I hope (and believe) his new life is sufficiently emotionally fulfilling - but he could have had it all.
