hmm, how to start ...
I read your description, and my heart vibrated reading the acronym C.M.B.Y.N.
I honestly loved the movie, and when I read his book I was fascinated with quite a bit of loving babble (Elio's thoughts, of course), but this brings back bad memories, because of that goodbye, because of Oliver (Armie Hammer's not so bad ... good).
I just wanted to tell you that I cried a little. Memories kill me, man :(
