I don’t feel safe around my extended family

Years ago, my cousin (who I hadn’t seen in a long time) messaged me on Instagram saying she was following and DMing my husband. I told her I wasn’t comfortable with that and asked her to stop. She told me that it’s something she and her sisters do with each other, and I explained that I’m not her sister and I’d appreciate if she respected my boundary.

Instead of backing off, she freaked out and involved her older sister. The older sister lashed out at me and said extremely nasty things. I blocked them both. After that, I started receiving constant harassing phone calls from one of their friends. It escalated badly — calls included someone screaming like bloody murder and a man making masturbation sounds. It was terrifying and deeply traumatizing.

It got so serious that my mom warned them there was already a record with the police and that if they continued, further action would be taken. After that, they finally stopped.

However, over the years I’ve still occasionally received random Instagram follows and DMs from my cousin. Each time it reopens the fear and anxiety. I went into a deep depression back then and genuinely feared for my safety.

This morning, after years of silence, I got another Instagram DM from her saying she got a new account, wished me Merry Christmas, commented on my life, and said “I miss you ❤️.”

I feel physically sick over it. It feels like she just refuses to leave me alone, and like she’s pretending none of the past ever happened. I have no desire to reconnect and I don’t trust her intentions given the history.

Am I wrong for wanting to block her again and keep no contact permanently, even though she’s technically family? I find it so creepy that she made a whole new account and it feels like she’s just using it to reach out to me.
