I'm glad I'm in Brussels where there's lots to distract me from my reaction. And I'm glad I'm not 28 any more, because when this kind of thing happened then - and believe me, it did! - I would have written back a very emotional letter defending my integrity foremost; whereas now, I can just look at the facts, convey them to rel. in a straightforward way, and hope that clears things up.
My heart is really with rel., who must be feeling that someone they loved betrayed them, which is one of the worst feelings in the world.
