Okay, if you are there when he reads it, then what? Do you have expectations of discussing it right then? If he does not say anything, are you going to ask questions? Do you have a plan of what you want out of being there? If not, I still think you give it to him to read and tell him you will be there when he wants to discuss it.
That being said, I don't know your H. Maybe your C is right. Maybe not. Her take that your H will avoid you if you are not there tells me that she thinks you should confront him if he does not have anything to say. If you don't, he is still avoiding you even if you are sitting right there, no? Why else would you need to be there? I can tell you with certainty that if he is not ready to talk about it, a confrontation/direct questions after reading that letter will go no place but downhill. You have every right to ask anything you like of him. You might even need to at this point to start living your life for you again. Just be prepared for stonewalling, lies, and counter-accusations...
Questions - Are you or your H religious at all? Do you pray?
Take care.
