*If a parent didn't have the insight to provide, it's their responsibility to be truthful regarding that fact- They could say, " Jack/Jane, I'm sorry about the difficult situation you're in and sorry that as a parent I had no knowledge or insight to provide you with in advance- Thank you for helping me to understand you, your circumstance and teaching me about something I wasn't aware of- You have my support-"
Instead of, "It's all his/her fault-" Meaning the the manipulative partner- Because it will only lead to distancing, defensiveness and eventually estrangement- *
I do understand what you are saying rosecarmel. However that conversation rests on the AC being aware, able to acknowledge the situation that they are in, or even that it is difficult. A pattern in coercive control relationships is that the victim takes many months/years, if ever, to actually begin to recognise/realise what is happening to them
In the context of conversations on GN posters who are EPs are not speaking to their children when they post, they are describing their perceptions of what has caused the problem to Gransnetters. That does not make it a given that they have told their estranged AC (before the estrangement) that it is all the ACs partners fault. They may have done that, they may not, But the fact that they express that view on GN does not mean that they have or have not had that conversation with their AC.
Some EPs on threads have acknowledged some sort of version of the conversation you describe with the ACs. Some have described how the AC was unable to acknowledge what was being said because they were unable to acknowledge their own situation. Other EPs have described how, after differing lengths of estrangement, the AC has contacted them because they have started to realise the situation they are in..in a coercive controlling relationship. They have contacted because they know that their EP will still step up for them , despite all that has happened. Some of those estrangements have ended as a result, with ACs acknowledging that their relationship caused the problems.
I cannot immediately reference the posters and anyway I wouldn't want to because it is their story to tell in whatever thread they wish to...plus I know some no longer post on estrangement ...they have moved into a new era with their ACs. Which is very positive for them and for their ACs presumably.
The estranged child isn't accountable for, nor responsible for apologizing for parental, knee-jerk reactions to complicated matters-
No the estranged child is not responsible for parental knee jerk reactions. But it is not a given that there has been "Parental knee jerk reactions" in every estrangement.
Estrangement is such a multifaceted thing and parenting is only one part of a very huge issue isn't it.
