It must have been very emotional to show him that letter. I don't even know how you could have hidden cancer treatments from him. He must be blind. And if someone is so blind to you, then it is that much harder to reveal so much of yourself and so fully. The letter is beautifully and movingly written. (I used to teach creative writing) You did an excellent job of telling your story without being condemning of him. If he feels guilty it is not because you made him feel guilty. It is because he feels guilty from the inside.
