That's great about D12 counselling.
I dunno, I agree with Alison that life is never as stable as we assume it is. Life can turn in a different direction in seconds. We think everything is stable but that's an illusion.
That said, I think the defining feature of limbo for almost everyone on here is that the spouse has the power. Whether that's only temporary power or whether that power changes isn't that relevant, we are waiting for our spouses to take some sort of action to move on from limbo. GAL is taking some of that power back, but the spouse still has most of the power because they left/are leaving/are having an A and yet we are waiting for a resolution of some sort.
Some days I feel at peace being in limbo and feel acceptance, other days or moments I rage against it and cry and vow to take action. Then back to acceptance.
