The only things he has said publically about his family are feeling Meghan was not welcomed, caring about his father's health and a sense of injustice at being the spare.
I've got no sympathy (and I don't know why he expects any) for him being the spare. If he had any perception or intelligence it would be obvious to him that his situation is the enviable one. He must be so childishly jealous and entitled!
As for Meghan not being welcomed, all the evidence is the other way. I think Harry is incapable of thinking for himself and almost everything he's said post-Meghan seems to originate from her. Meghan whinges to Harry - as part of her eternal victim persona - and he just accepts what she says rather than actually looking around him, listening to what people are saying and engaging his brain to make his own judgement. It was ironic that in Spare Harry reported that William complained about Meghan's treatment of staff, and while H acknowledged that staff were 'crying at their desks', in the same breath accused William of parrotting the media view of Meghan. What?? It makes no sense.
Only the biggest red carpet on the planet, her own enormous crown, at least one huge palace or castle, an unlimited clothing budget and possibly the promise of becoming Queen instead of Kate would satisfy Meghan's idea of 'being welcomed into the RF'! 😂
