Help please 😩😔

So my bf and I have been together 3 months, and his ex just recently found out about us (they were together 15 years and she cheated on him) they’ve been broken up for 9 months. Anyway now that she knows about me all hell has broken loose. She has filed a false protection order against him taking him to court saying he domestically abused her (which he did not) now shes not allowed with in X amount of feet from him. She lives in my neighborhood (lucky me right?) she has literally been stalking us, follows us after we get off work and just last night she starred at my house for 15 minutes straight whilst I wasn’t home (my neighbor told me about it). I no longer know what to do, I don’t want to be in this kind of situation where I feel like I can’t even leave my home or go to work without being watched. I’m afraid she may hurt my family or I, I’m completely lost. I love him and I really don’t want to leave him when it’s not his fault, but at the same time I can’t live my life in constant fear and worry. My anxiety has come back after months of it being gone and I’m just so sad. Can someone please help me? 😔
