She said, "I hope I loved him enough."
Those who live after you will suffer, surely, from guilt, particularly as you, although I don't know you, care for those who will live after you.
They may well wonder if they should have done this rather than that and go over and over what they might have done differently, not understanding that anything they do or say will always be wrong because nothing can ever be right about losing someone you love.
I was the one who broke the news to my father that he would not be cured because the rest of the family was in denial as was he. I vowed to be honest with him because of my acquiesce to the familial denial I knew was wrong when my mother was dying. (In my father's case, had a frank conversation with the oncologist based on my literature searches.) My guilt over my mother's case was somewhat assuaged when I realized I felt equally as bad about being honest with him as I did in lying to my mother and telling her we would beat it, although I alone in my family knew otherwise.
In these final days of your life, you are involved in love, and I hope, when my time comes as inevitably it will, I will have the wherewithal to be so myself.
I wish you peace.
