I am a bit stunned by the latest posts, tbh.
Firstly, I think most people are happy to point out they are neither psychotherapists nor counsellors, and many are equally happy to cite personal experience where relevant and sometimes not. We all bring our own baggage to the table. es, I had a lousy childhood, and could be accused of having serious mother issues which I may have brought to the table..... but as it happens I also went through a truly dreadful time with my DD aged 17-19. Years I would not want to live through again. So as far as I can see, that experience comes to the table as well, and balances things out.
I see this thread very differently. The OP was starkly challenged on the first post because few responders saw it as an OK response to the daughter. Challenging is a good thing.
Replies could have offered a broadscale "you were right, go no contact and the hell with it". Personally, I can't see that responses of that sort are of much help to anyone. Those of us who did post - me included - asked the poster to come back and talk. To explain more.
And she had the courage to do that. At which point, a lot more of the story came out. Including the long-term difficulties with family issues. At which point the tenor shifted to a more supportive mode, and the OP began to ask real questions about changing things.....and most importantly, began to view things in a wider perspective. She then asked how issues could be worked through.
Once past the first post, and the OP had given some some insight into why things might be happening rather than just venting, people who had stuck with it became more supportive of the OP - actively suggesting she could take charge of managing the situation, and could make positive change to the way she handled things. Hopefully giving the chance to improve how both she and her daughter feels.
How this relates to being told she should "run for the hills", I have no idea. As far as I can see its about telling someone that they don't have to be the victim of past experiences, but can move forward positively. That's empowerment.
I absolutely believe that where it is possible, the best way to open dialogue between warring parents/children is for one party to have the courage to sit down and say "I am listening". I want to hear how you feel". Because that opens a basis for discussion. It does not mean taking the blame - beyond apologising for where you know you erred - and it does not mean never being able to say your piece. But unless someone climbs off the high horse for long enough to fix things .... relationships can stay broken for a very long time, perhaps permanently.
OP - take what you will from this thread. If you view it as a car crash, then ignore everything and run for the hills, as suggested. If anything that was said has challenged you to look at things differently, and that works for you, ....then great. Either way, I hope things work out well.
