I would put the letter in a sealed envelope and give it to him, telling him what it is. I would tell him my fears concerning his reading the letter, and ask him to consider that before deciding whether or not to read it. But the letter is his. You won't hide it or anything else from him.

As for asking for constant accounting of thoughts of OM. I thought the whole point was to forget OM. I would say, I am trying to forget him. I don't think it is good for us to dwell on him. Can we hold off on this til after Retrouvaille? If they tell us that is a good thing to do, then I'll do it. In the meantime, it gives me a month or two to just put it out of my mind.
