Dear Joan,
I don't think there's a one-size-fits-all on this. Some people really want to know where they are on the journey. Others prefer to believe in a miracle happening, right to the end. There's no right and wrong.
I would trust your instincts, though, knowing him as you do. Emphasize that you are going to be with him and will never stop looking for ways to make each day the best it can be, for him to be safe and comfortable and painfree. We all know by now that when you have serious advanced cancer, no one can say exactly what will happen each day. Too many bad and sad moments have taught us this. But we can promise to each other that we will not let each other down in terms of love and affection.
Hope you have lots of support. Accept help whenever it's offered... may it be offered often. But also take time to be by yourself when you need it.
Peace,
Sarah
