Abusive breakups

Hello, so I dated this guy for almost a year any ways he was abusive to me. He did so many things to me he raped me, cheated on me, pressured me to get him something when I had money, let his friends be rude to me, always told me how I was being a bad gf, I tried to break up with him several times but he always found a way to get me to come back, he would blame his cutting on me, one time he drove to some location where he said no one would find him he sent me pictures of where he cut. And said he needed me I had to call one of his friends to go save him. And got the location out of him by telling him I was on my way to see him. Anyways I broke up with him almost 2 months ago, he now how as new gf for 1 am terrified he is abusing her also, 2 we were talking a bit before and she just in the middle of us talking tells me that he dosent wanna talk anymore. It happened twice and I am not sure if it was her or him because he told me I was special to him in ways I would never be to anyone. On top of that because he raped me I don't feel like I will ever be able to trust- love or date again it makes me super angry that he could just move on like that. I sent him a letter in the mail finally feeling like I had my voice again but odk if he got it yet and I am scared he might blow up my phone or something when he gets it. I know I should block him from my phone but I can't he still needs to send me my stuff.
