My heart is breaking for you. I'm so sorry. I'm sorry she's going through it and sorrier for you having to watch her, and lose her.
I have never wanted to be able to reach through a computer and hug someone harder than I do right now
May you find what comfort there is in the arms of your children and grandchildren. And you were her soulmate too, so I'm sure (if you'll forgive me for saying so) that she would not begrudge you this reconnection at this time. It's not taking anything away from her or your family anymore.
