perhaps he will drink himself into a stupor today and leave you in peace...I know this sounds mean, but if he's passed out drunk somewhere he won't have the energy to bother you.
now in my dry wit matter, you might have to leave a bottle of vodka on the front steps in the future? would he take it and just go away? anything to avoid his high paranoid drama?
reading your postings dredges up my own horrible divorce and crazy Xhusband (who died in his sleep at age 54 and was found by his mother)...all I can tell you is that after the divorce is over, the *stuff* should calm down as the kids get older. i hope you get some relief today.
