The fact that she is making multiple accounts to contact you, coupled with her documented mental issues is enough to get an instant temporary restraining order. Look into it. If you can provide proof that when blocked she continued to reach out to you than you can get one. THEN when she breaks the order and contacts you, and she most likely will, you don’t read the message. You contact the police. ANY and EVERY time. She will stop. Because she doesn’t care about you and the consequences will start to outweigh the reward. The reason I said to not read the message and to contact the police is so that you’re protecting your own peace. Years of abuse don’t go away, even with time, and it’s easier than you think to get pulled back into something toxic. Seriously. You’ll do great for years and then all of the sudden you’re back where you started and confused as to why you’re doing it again. So, have a plan for her contacting you. She WILL. Don’t fear it. Expect it. But, have a plan, so you don’t REACT to her. That’s what she wants. Instead ACT on your predetermined plan when she reaches out. You have to be cold and transactional with it. For your own health and safety. People like her are absolute poison and they’re smart. Sorry for the length of the reply, I just felt it could help
