Gwen (apologies for threadjack) but a good while back someone identifed MLCers in their early stages as either Dropouts (vanishers) Drop-ins - those who stay at home pretty much throughout the crisis (or would if not sometimes ejected by their exasperated spouse), and Droplets who come and go/stay in intermittent contact - again if permitted.
My xh was a vanisher. Now he is in sporadic contact with me - so who knows?? It is out of our control that is for sure.
