Yes, I have. I think you need to notify the police now and give them his name/info and tell them about your situation. See what they say. Also, law enforcement will do a free check inside and outside your home and tell you how to make it more secure.

Block him from all possible contacts, phone, social media. If he has ever touched your keys, I'd change your locks. Check your car for a GPS monitor. Do not contact him. No contact. If you see him, reverse direction and get away. Get pepper spray...sold at hunting or sporting goods stores. Keep it with you.

I chose not to get a domestic violence injunction. This was a personal call I made. Depending on a stalker's personality, this may enrage them and d.v. Injunctions...it's a piece of paper. But you use your judgement.

I can't advise you on guilt, just what steps I took in my situation.

Stay safe. xo
