I like your thinking about detachment. That is where I want to be, at the moment I am doing great with the NC, day 7 and holding strong. I think less and less about what W may be doing and that is releasing me to GAL. THe exact result I was hoping for.
If and when contact starts again, if we have to meet up, then I need to be aware of myself and remain in the detached state. That way I won't be feeling all sorry for myself when I get home. I feel like I am getting there, but not quite ready for that yet.
That's what this club is for, help, a watching brief over our own sitchs and a 2 x 4 if we mess up.
