So sorry to hear about you and your mothers sadness. It is so hard when demential is the culprit. When is the person really gone? Like you said, not to wish him gone or anythiong, but it will actually be a blessing for him and everyone that has had to watch the process. All my best wishes out to you dear mother. She will need your support more than anything when this drama is over for her. Maybe mom can come stay with you for a while during the adjustment period. Keeping your family in my prayers.
