I've been thinking about this for a while.
I am estranged. I don't miss those people [shudder!] but I do miss being part of a family. And I really feel for my kids who have so little family in their lives.
I feel that the Stately Homes thread is great for dealing with the inevitable interactions and stresses with people who are just no good for you, but I felt I wanted somewhere just to think about the reality of being an ex- family member.
Also it worries me when people recommend going no contact (nc) at the drop of a hat. It's a really tough way to live.
