Please Help Any Advice Would Be Greatly Appreciated

I’m 23, and my toxic partner (almost 33) has been abusive throughout our 3-year relationship. Every time I try to get space or set boundaries, he escalates his tactics in ways that fly under the radar legally. He has multiple devices (iPhone, Android, laptop, tablet) and extensive knowledge of hacking, coding, and social engineering, which he’s used to intimidate me. He had a suspended license for over a year and just got it back a few days ago and with his new freedom he’s been more bold and confident. I have no friends and he’s sabotaged every job I’ve ever gotten.

At the moment I keep getting password reset codes for my iCloud and emails about login attempts I didn’t make. Even when I block him, he harasses me from endless new numbers and even disguises his calls to look like my sister or cousin. He even has hacked other people’s facebook accounts to try to befriend me. I don’t know how to prove this or what steps to take. My fight-or-flight is constantly activated, and I feel lost. Any advice on safety precautions or legal options would be deeply appreciated.

Steps I have taken include checking all my socials and any other accounts to make sure my passwords and recovery measures are up to date. Along with making what social media I do have as private as possible. The only family I have (my sis and cousin) are aware and I’ve warned them to be aware of accounts and other activities from people they don’t know.
