My boyfriends past female friend is obsessed with him and has been calling him even though he blocked her, I’m concerned for safety?

So my new boyfriend used to live with his female friend who he used to have sexual relations with, as apparently she kept walking around naked and tempting him etc. He said that she was quite obsessed with him.

Now he lives in his own place. He has her blocked, but she still attempts to call him through different numbers or accounts on Facebook etc. She also knows his current address. I’m worried if she somehow finds out about me she will get angry and I’m kind of worried about my safety.

Am I overreacting? If not, how can I keep protected?
