You two seem to be having a private conversation but, as it is public, I feel entitled to contribute.
The daughter of grahamg is now an adult....a highly intelligent, educated woman with a professional job. She is fully capable of forming her own opinions and her own judgements. She has decided she does not want her father in her life, and doesn't want him to be part of her children's lives. What does that indicate?
I have decided to try to give you a better response than my previous one, (or at least use your post for my own purposes!).
As far as your description of my daughter goes everything you've said about her is accurate, and you could argue that without the reference to my grandchildren, her offspring of course, everything you've said applied equally as well when she was twelve years old, (though till that age my daughter telling me I was horrible, and she hated me was always followed by "Keep coming daddy"!).
As to what it might indicate, (so far as me as her father goes being the implied question), I can repeat what my daughter told both my parents aged twenty one, when visiting their farm to be told I was next door if she wanted to see me, and she said, "Her mother and stepfather were against it, and she had to live there"!
At the next opportunity to meet, a couple of years later, similarly at my parents farm, I was told I was permitted to be present, but no explanation given for the change of heart on whoever's part, (my belief being her mother didn't like my parents being told the truth two years earlier, hence paying lip service by allowing me to be there, but then my daughter treating me with indifference I think it is fair to say, fulfilled the bill for the other interested parties!).
Moving on to pointing out some anomalous situations thrown up by the way UK family law is framed now, in order to try to undermine some of the blind faith shown in it, and the legal principle its based upon, it is true that:
"A man who has not abused his children, and did all the things listed in the OP who is dying of cancer, cannot have a court decide on compassionate ground to allow him contact with his children as the decent thing to do, but rather has to try to argue why it might be in the children's interests to see him".
"Our queen, when Prince Charles and Princess Diana were separating prior to divorcing, faced the prospect of not being allowed to see Prince William and Prince HarryHarry, (this being discussed on the BBC by royal observers and experts). Thus even being a head of state in a monarchy does not confer any rights to contact with grandchildren in the UK, regardless of the service to our country our queen is being so rightly praised for so much now, (to be topical, though in the event Princess Diana's love and respect for the queen meant she never created any obstacles to the grandchildren seeing her).
Those two statements above, should be added to the words of Goldwater, the young Canadian lawyer in 1992, describing the need for privacy in close personal relationships meaning I believe it was harmful to those relationships for the state to deny this, (and Goldwater went further, pointing out "the moral failure in smugly asserting children have tights, whilst ignoring their obvious vulnerability to manipulation and control").
Finally a contributor to the world congress on the child, organised by the united nations I believe, almost forty years ago, was addressed by professor Akira Morata who told the gathering "it was the relationship with the patent that the child needed, not some notion of children's rights"!
Thus laws based solely on the interests of the child, or putting them above all else all the time, ignores a fundamental factor inherent to bonds with our children, the interdependency and mutual interests aspects of each ultimately cooperating with the other, ("through thick and thin"!).
