Hacked and treated like property

I dated him for less than a few months back in 2020. After the breakup he began hacking my home wifi and all devices on it. I spent years changing passwords and devices which cost me thousands of dollars. Regardless of how many times I replaced them he hacked the new ones within hours. This continued for nearly a decade. FBI, SBI, and local police did not investigate him and likely never will. When an immediate family member died, he destroyed my laptop with the damage he did to it from all the spyware, effectively isolating me at a time I needed support. He preferred I only think of him rather than grieve a lost family member. When I attempted to go back to university at my dream school he hacked the access point there and all my devices on it. His spyware survived multiple factory resets and he damaged my laptop which caused me to nearly fail out of university. When I got a decent job after graduating he hacked all my devices when I moved again. He would crash the network multiple times a day every day while I worked and sign into my work email changing the background multiple times a day. Each time I reported him even on my phone not on wifi he would crash the network for hours preventing me from being able to work out of retaliation. When I would buy new devices, they would mirror his browsing as if I was browsing as him and vice versa. He put high level spyware on my computer and phone tracking my photos, texts, and activities in real time. He would also play music like the song “Sucker for Pain” which discusses taking pleasure in torturing someone while hacking my devices. To this day he refers to me in derogatory terms such as a narcissist, immature, delusional, etc and people believe him not knowing the side of him I know. He lied to people telling them he broke up with me because I was “too immature” for him. He often spoke of other women he dated previously in similar terms to me, but I never realized it was just a pattern that I would be another continuation of. I regret not seeing the warning signs earlier. To date he is in his 40s and still takes his anger at his mom who abandoned him out on me, because apparently that is easier than him seeing himself for what he truly is. He would rather feel powerful through whatever means necessary than acknowledge how powerless he actually is and his lack of self-control. Regardless of what he does to me, I often think about how weak a person would have to be to go to this extent of evil to feel they are in control of their life.
