Should I just not talk to anybody new?

My ex ended our toxic relationship a few months ago and want to make friends. But I’m scared. My ex is super crazy. He was highly abusive in every way, super manipulative, narcissistic, etc. His whole family, a group of friends, and even one of his coworkers abused me (emotionally) and took part in games he was playing. He admitted to watching my social medias and I’m pretty sure he now uses third party for that too. He cheated during both our kids’ births. He’s made threats to kill me and just choked me a few weeks ago. He also used a third party to try to get info on where the kids and I are living, to try to convince me to move home, to try to convince me not to date, tried to get with me both romantically and sexually, and to try to get me to go to a hotel room with my kids with him. He also uses third party to try to get my kids alone. My restraining order against him got approved and served super quick. He cannot reach out to me or come to where I am living, which is a relief. But now I am paranoid that anyone I come into contact with, or even some that I already know, are somehow connected to him and will keep tabs on him for me. And I don’t want him knowing anything or being able to continue to abuse me from the background. I finally got away from him and I’m happy
