PS - I think it is guilt and confusion that prevents them sleeping in the same bed with us. If you remember it is one of the 'signs' of MLC -'Hanging on to the edge of the mattress'.
My h could not sleep with me when he tried to come home - it was my fault of course!! They are wracked with shame and guilt, just in total denial of it. .When they start to face it is when teh possibility of recovery begins
I think that all we can do is to keep going, and eventually, one way or another we reach a point when we are all right. If our spouses are alongside is actually their decision. I share BND[and others] views that we are the pearl of great price. That they cannot see it is their loss.
