I saw the Gransnet thread. It's very difficult to read, though it has been interesting to look at the deeply toxic nature of perspective taking in all of this, and the idea that some people "cut off" parents because of trivialities. I don't think the research would support that.
I have spent nearly my whole adult life trying desperately NOT to be NC with my father and I am not "technically", I just don't respond to his drunken phonecalls or go to visit anymore except at Christmas. I had to make that decision because of his treatment of my children.
It strikes me it must be a very desperately lonely place, to be so cut off from having perspective on your own actions that you can't understand why a child is not making contact because you can't look at the reality of your treatment of them. To view your child's anger as evidence they have no love in their lives, but your anger as justified and coming from a place of love. To view your hurt as real and arising in the relationship between you and theirs as entitled as arising from cultural expectations that have nothing to do with your relationship. To view their pain as irrelevant to anything you have done or failed to do, but your pain as a product of their abuse of you. To view your "rights" as important and obvious, but the very idea they have "rights" as some weird product of a fucked up society. To believe you have rebuilt your life to have healthier relationships without them, but this couldn't be possibly true for them if you are not in their lives.
In the kindest way, it is such a deeply infantile perspective , a tantrum about the nature of reality - a sense that the world for others falls away when you are absent from it, that others are not whole without you as you are the missing piece.
I feel deeply the sadness that there are parents who genuinely never learned that they cannot be the centre of their children's lives, that what children most deserve is sovereignty and to be let go to live their own lives as they see fit without any reference to you. And where parents can and do allow children that freedom, relationships can be wonderful. I certainly have that with my mother, and yet my father still has this notion I will "end up alone and unwhole" without HIM - because all the other people who are and have been constant and supportive in my life (my mother, stepfather, grandparents, inlaws, siblings and wider family) are pale sad shadows of the wonderfulness of him.
Ah, Daddy. You poor man. That's just not true, as much as you so desperately wish it were and have this abiding need to convince yourself you are more special than everyone else in the world.
I actually have a lot of compassion for that "toddler mind" perspective, and I can see it is arrested emotional development on the part of very deeply wounded individuals, and yes, there is sadness that this is part of life.
Of course it would be better to also have a father in this mix of life, but life doesn't allow that to many people for a variety of reasons and in my case it happens to relate to him being deeply damaged and broken in ways that are beyond my human capacity to accommodate. I don't hate my father but I do find it very hard to accommodate that he could have chosen to be as abusive as he was to both me and my mother.
I also find it very sad that the justification that is used by many is the idea that people seeking happiness is the problem, that there's an unhealthy individualism to it. The sad part is that pain in life IS inevitable. People will die, bodies will age and deteriorate, all relationships change in intensity over the lifespan. But THESE are normal things and it is the failure to allow them that creates the situation where estrangement is inevitable - where they can't let go in healthy ways and continue to abuse us as adults.
We can't turn away from the pain and longing of loss but we can stand firm and say I will not allow myself to be treated as an extension of you instead of an autonomous person in my own right, with an innate right to have relationships with other people who value my autonomy and do not seek to destroy or abuse it.
I am sorry my dad couldn't have been able to just live life in a loving way. That is a source of deep pain. However, suffering is a different prospect. Suffering is thinking things should be other than what they are and thinking the past can be unwritten because it has led you somewhere you wish you weren't. It is what it is. I'm not angry with him, I just wish life had been kinder to us all.
