Dear Majo 
I am glad the other folks were around and you feel better already. After reading though i hope it's ok if give my thoughts on the situation. which in brief is, indeed, don't believe it, but i don't even think he believed it....
Whether you made some mistakes or not I don't know... i don't use facebook precisely because i am afraid of social messes between people i know more, and people i know less, different circles, bla bla.
what i DO KNOW is that
you a sweet, kind, sensitive person,
not evil. i mean!


and you know, i can't really even take it seriously... think about it for a minute: if you thought someone was a serial killer... would you go up to them and
tell them you were afraid they were a serial killer? YA! RIGHT?!!! i'd maybe cancel the show... if for some reason i couldn't... ok i'd go, but keep a low profile, keep my distance, minimum contact. i'd
certainly not go and say all those things to someone i
truly believed was a dangerous social element and "evil". so, i'm thinking that he perhaps felt offended by what he read/understood from your fb page... perhaps he didn't grasp that you were joking (or didn't think the jokes were funny since they were about him) and decided to get back at you in a VERY MEAN WAY. i don't even think he thought what he said. imho.
i wonder if that guy has some streak of sadism. perhaps some other mental issues like the rest of us (paranoia may destroya). at very best, he is very immature - he takes no responsibility for his feelings or even his own actions (guitar player relationship is between the two of them - gimme a break!)
Furthermore he becomes vicious if he feels in the least bit dissed (defensive maneuver at best, sadist at worst).
if he needed to get things off his chest, he could have confronted you about what was said that bothered him without making off the wall accusations.
do you think they take drugs... well i'm thinking you might not have realized it if they did... they might not have been high when they were there but it could explain some of the excessive reactions/interpretations. no excuse though.
so just hang in there. i am so sorry your party & concert got dashed by what should have been the very highlight.
I send you much love


and warm hugs


and good thoughts.

p.s.
i am proud of you for considering, after all his initial insults, that perhaps he might have
felt offended, and apologizing. that was very kind of you. the fact that he couldn't even step up to that shows what a seriously messed up piece of work HE is.
