The only further point I wish to convey about last night is the following thought: obsession, of the kind you described, that goes on for years, and is not reciprocated -- it isn't real, and it isn't love. It's something else, and it isn't good, and there's only one way to treat it. You have to tear it out by the roots.
Of course, you should feel free, as you have, and as I'm sure you will, to disregard this truth. But you should hear it, so as not to be able to say, at some later point, that you were never told.
