Suspicious emails not blocked

wroot I was curious since these responses are dated back to 2018, have you been able to learn how to report such phishing? I’m the victim of cyberabuse with the abuser continuously and maliciously using any form to harass. With that being said, I received just the other day, Sept. 2022, the exact same phishing email message header BUT the email itself was from the individual due to having children together. The email body was of a normal message but knowing his history of hacking I analyzed the email and it came back exactly what this discussion was about to a ‘T.’ I know he’s a hacker, has hacked many of my accounts, he’s violated a restraining order on many occasions, how can I report this and is there any way anyone reading this knows how I can prove the hacking?? He’s escalating and that puts me at a high risk for my safety and our children’s. Please if someone can help me find ways to prove and use to hold him accountable, it would be much appreciated.
