Hello Ella: I see this is your first post here on PC. Welcome to Psych Central. The Survivors of Abuse forum, here on PC, is one you may want to check out. Here's a link just in case you haven't already found it:

I'm sorry I don't know as there is a lot I can offer with regard to your situation. Hopefully there are going to be other PC members who will have some insights & suggestions they can share. My own personal gut-level reaction is that you are being sexually harassed & should report this stalker to management & perhaps even file a report with the police. But I don't know if these are really the best steps for you to take given your circumstances. If, by some chance, there is a women's advocacy organization where you life, perhaps talking your situation through with someone there might be helpful?

You mentioned you were sexually abused as a child. So here are links to 6 articles, from Psych Central's archives, on healing from childhood sexual abuse & related topics:
