Sure. But definitely fear.
Everyone who is in a happy marriage knows that the worst day of their life is coming and it will be agonizing.
It will be the day when you know your husband or wife is dying and there is nothing at all you can do about it. You may try but in the face of that final moment you are helpless.
She got hit with it earlier then most people do but we all eventually run into it.
In her case she is doing her best to try to postpone that day as much as she can. And so is he.
So.
Love.
Which casts out fear.
