i do believe there are ways to do this. someone i know who was married for almost twenty years,with the advice of a good lawyer,got a restraining order and divorce papers started all at the same time...so that he was served the r-o at least--cant remember what other papers...the same day she changed the locks.they went to the first court hearing within a few days,and he could not return without police to get what he needed.
i would think with all that drinking,seizures,verbal abuse,etc...that he would be considered a threat to himself or others.and that is supposedly all thats needed to get the r-o,or a person committed to somewhere.
and yes,there is light at the tunnel. we expected the worst when the girl i know did all this.....and though he acted (and still acts) like the usual jerk he was,he wasnt as bad as anticipated.
do your research,try a couple lawyers opinions.............and i hope for the best for you.
