Well live in fear is strong.
But I always have the horrible, nagging feeling they will pop up.
I have two family members that I cut out of my life around 20 years ago now. We don't have a large family, so it's not like we see the same people or anything.
I never want to see these people again. They were awful.
But a couple of years ago one tracked down my ex husband. Who took great glee in telling me. They basically re wrote history, said some horrible things about me. It was nasty - of course my ex read the whole message and the reply he said he sent which was basically agreeing. Even though I went NC when we were together and he was the one who helped me come to that decision after witnessing their behaviour on several occasions. I was very upset that he had engaged with them.
So he's the only link in the chain.
Although they have tried to use their teenage children to find my teenager on social media and sent messages, which my teen has shown me and blocked (he's 19 so knows what happened).
I still have it hanging over me that one day they will find me and I can't let it go.
