Seeking Guidance on Reconnecting with Someone from My Past

Assalamualaikum, I hope you’re all well. Sorry this is a bit long, but I’m feeling really uneasy and could use some advice from my Muslim brothers and sisters. Someone from my past, who I haven’t heard from in years, just reached out to me. Every time this person contacts me, something really bad seems to happen in my life, and I’m torn about what to do. A few years back, I lived with this person for about six months. Suddenly, he told me to leave because his parents were visiting and didn’t know he was renting the place to me. Since then, I haven’t been able to find a stable home and my mental and physical health have suffered greatly for over six years. We fell out after I found out he was involved in illegal activities to make money. Around the same time, I told him I was struggling with suicidal thoughts, and his response hurt me deeply - he spoke harshly about a friend who died by suicide, calling him selfish. This crushed me inside. Soon after, I suspected him of trying to hack my accounts, and when I confronted him, he blocked me. Oddly, I noticed he became certified in coding during the same month as my birthday and married a woman who looks like me. About three years later, I even apologised to him for both telling him about my struggles and for suspecting him. I felt like my feelings were completely ignored. Spiritually, before meeting him, I was coping despite difficulties. But while living with him, I started experiencing strange spiritual things again - things I only saw when I was younger. He even admitted to witnessing disturbing spiritual events. Now, whenever he reaches out, bad things seem to follow, and I can’t help but feel a heavy, negative energy, though I don’t want to accuse him of sihr. I’m confused because he was the last person I remember being physically healthy around, but at the same time, his presence always left me feeling spiritually drained and almost cursed. I grew up in foster care with no real family support and have survived a lot, but my health really declined after living with him. Now, I’m scared to respond or let him back in my life - but I also miss the healthier version of myself I felt around him. I’d really appreciate honest Islamic advice on how to protect myself spiritually and emotionally from someone who might be harmful but still has a strong hold on my thoughts. The last time I reached out to apologise for things I shouldn’t have had to, we stopped talking. Since then, I reconnected with my family after nearly 20 years but have faced domestic abuse and even attempts on my life. He just contacted me again after over two years, and I feel a strong sense of the evil eye from him. He’s the last person I felt healthy around and might be able to help me if he truly wanted to, as he has good connections and once offered to help me find a job. I refused because I was ashamed to share my background with him. This contact comes at a time when I really need help. I grew up without family because my parents lost custody. I’m an adult now and recently decided to forgive my mother for her abuse and neglect, but I’m trapped at home with her. Every time I try to leave, she calls the police with false claims. She’s admitted to practicing black magic and has confessed to poisoning my father before the divorce that sent us into foster care. I’ve informed the police about my fears for my safety, but nothing has been done. She once gave me food I don’t usually eat, and after eating it, I collapsed and was unable to function for eight weeks. I might share more about my situation when I have the strength. Right now, I’m wondering if I should reply to this person who I suspect has been casting the evil eye on me since I left his apartment six years ago, which coincides with when my health started to fail. At the same time, he’s the only one who might genuinely help me if he chose to, and I never saw him do anything spiritual, though he comes from a very spiritual background where belief in the evil eye is common. He had many evil eye beads in his apartment and shared some experiences that made me feel he might be spiritually troubled. I’m really lost and scared, and I ask Allah to guide me and protect me. JazakAllahu khairan for any advice you can offer.
