I agree with the other posters like sarahsweets and StreetcarBlanche about calling the police, @vesseloflove. Even if you don't have evidence, they can at least put an eye on him and if anything illegal shows up they'll be able to catch him in the act. At the very least, you'll know that you've done your duty. Anything further is out of your zone I'd say. I also agree with URBeautiful about talking to your supervisors about this if you're struggling. I'm sure they will be able to help you. Surely this is not the first time they've had to deal with a situation like this! Let us know how things turn out and please remember to stay safe as your own Life is a PRIORITY as well. Sending many safe, warm hugs to BOTH you and ALL of the people involved in your program, vesseloflove!
