HUrray for you!
I've been through some doozies of therapists over the years, and I can see the flags you raise right away, in the punishment of people who have left: that is just a tactic to scare the ones who remain.
Personally, I would leave a clear message on record or in writing that no contact is desired. That way they can't chase you around claiming you need "help". Here in Texas, anyone who violates that kind of message can be charged with stalking and it does not have to be sexual to be taken seriously. There is a page up by the U of Tx that says law enforcement considers 3 contacts after such a message to be crossing the line. Find out what your local laws are. They have evolved greatly in recent years on this subject of stalking.
