Mary Lincoln's presence at Abraham's death-bed

[LincolnMan]

I counseled a recently widowed female patient today. She told me how important it was to her that she spend the last few hours with her husband as he was dying. It later struck me that Mary Lincoln was deprived of this. I know there were other considerations to factor in pertaining to Lincoln's death-but Mary was, in the end, not allowed to be with her husband at his end. Was this an injustice to her? Was it unusual for the wife of a dying husband to not be with him the entire time? Was Stanton being inconsiderate of her? Why wouldn't it be allowed for her to show strong emotion at that time?
