I didn't know that people were not aware that MJ and Debbie knew each other for about 20 years. Aside from being his wife, Debbie was the Mother of his children, his friend, and more than likely his guardian too. To me, that's very close.
There were so many doctor's over the years who gave MJ strong pain medication that I feel if it weren't for Debbie, we would have lost MJ many years before we did. It seems as tho MJ was in a terrible position. He had to prepare for TII, but he was desperate for sleep and only Propofol worked for him, so in his desperation, he just trusted Murray to save him, and Murray did not save him.
