Narc no contact

I’ve been no contact with my narc emotionally and physically abusive ex for 4 weeks after a 2 year relationship and 3 years of on and off (the trauma bond was strong please don’t judge me).

In those 4 weeks they’ve sent me 2 emails (which I’ve ignored, email address is now blocked) created 4 fake social media accounts, followed me and anyone directly or indirectly associated with me including accounts with different variations of my name and my child’s name (my child isn’t on social media just extremely weird, now I’ve shut down all social media) and today they’ve got there friend to call me so I’m in the process of changing my number. I didn’t recognise the number that called me so saved it and then WhatsApped the number only to see the profile picture was of my exes friend so blocked immediately.

Chat GPT is definitely sick of me because every day with my anxiety through the roof I’m asking how to deal with the situation. I have contacted the police who helpfully advised they would ‘speak to’ my ex but nothing has happened. I’ve also contacted the national stalking line.

How do I make this stop? All I want to do is message my ex and say ‘leave me alone you freak’ but all the advice is saying this will just give them what they want, contact. I’m a paranoid mess. I’ve even brought a ring doorbell because I’m scared the lunatic will turn up at my house with all other forms of communication blocked and I have small children.

How do I make this stop? Will it stop? I can’t be living like this for the rest if my life my nerves are in pieces
