I do pray for her to have strength not to miss him too much. My grandparents were very much in love, childhood sweethearts who grew up around the corner from each other, hardly ever apart, and when my grandmother died part of my grandfather died too. I think part of his slipping away into Alzheimer's may have been from loneliness.
I think that the worst thing for Nancy, was not seeing in her Ronnie's face a mirror of her own expressions of love. When that stopped, it must have been like a light going off.
I hope you're right, though.
My parents passed away 6 months apart, so I understand what you mean about your grandparents. I truly hope that Nancy can *live* the rest of her life. This will be some difficult period of adjustment for her, because he won't be there for her to care for, anymore. God bless her.
