I know what you mean about not knowing stuff. I think the words the yanks use is 'closure'. lol
Ultimately, I reckon there's no point even thinking about it cause you're never going to know by the sounds of it. Can't really say what I want cause I'm pissed, but it's something about how not even getting angry or disappointed is worth it cause you're better than that. It's a cliche, but karma will sort him out.
