I suggested before that you call Adult protective Services. I still believe
you should do so. But with the way the situation is sounding I would
make sure you are allowed to talk to them at some other location.
Also make sure you let them know he is physically not afraid to enter
your premises when you don't want him too. Also for your protection
buy a small tape recorder and keep it hidden and tape the conversations
with him. Just in case
