Is this person still trying to harm me? (TW)

Hi! This is a little strange but I am hoping to receive some advice for this situation. Basically I was dating this man for two years, at first it was fine but it spiraled into a very scary, very abusive relationship. It ended with him trying to take my life because I ended the relationship. He was a very strange person and his behavior was very confusing a lot of the time. He was quite spiritual and would sometimes drop weird bits of information about him being watched or having energetic ties to certain things. He never really went into detail about it. When things started to get really bad, I was extremely thin and weak, I felt like the life was getting sucked out of me day by day. The night that he assaulted me, he was not on any substances and was acting incredibly scary. His eyes looked like black voids of evil, and they seemed devoid of any human soul. He told me a lot of weird shit like that I was a witch and I had powers?

It was all very weird. I somehow survived and am (relatively) fine now. It’s just that, sometimes I feel a weird energetic tie to this person. Like they are still trying to attack me? I get these random thoughts out of the blue to end my life or extreme bouts of fear. While I know I have major trauma from what happened, these thoughts seem more like out of nowhere if that makes sense. This person is in prison but I feel like they are still holding fear over me. Maybe this is just me being paranoid and I apologize if I sound strange. I just want to know if there are any possible spells, rituals, protective wards I can cast and use to cut ties with this person.
