rapist messaged my sister

Lucy • Law student
I got raped about a year ago nd now he's getting in contact with my twin sister. He's a fucking psycho and I should have got a restraining order. I'm pissed, humoured and upset all at the same time 
*edit* he's been calling my house phone non stop as I changed my phone number a year ago. My sister is aware what happened. He's been saying to her that he's outside my house. He knows where I live even tho he's never been there. And he thinks we're still going out :/.
Thank you so much for your support I didn't expect anyone to say anything, I just wanted to vent.
