My abuser is miserable and I’m overjoyed about it

About half a year ago, I (19f) started talking to this guy (23m), who seemed to be super nice and respectful. My friends and family loved him, because he really did seem great. After a few weeks, he got sexually abusive and raped me. He stayed that way until I left, but once I left he started stalking and harassing me, which honestly seemed much worse to me at the time. He used to threaten me, which made me *extremely* scared of him. A few days ago, he suddenly texted me again asking me why I had unblocked him. I didn’t respond but he somehow just continued the conversation with himself. He told me how much he is suffering and that he feels like no one ever loves him. He also is still hung up on the fact that I “just” left him- not in an angry way, but in a depressed way. It’s hard to put it into words and I can’t list everything he told me here, but trust me he is miserable. Nothing in his life is working out for him and I enjoy it. I know I shouldn’t be this happy about his suffering, especially because I’m Christian, but I can’t help it. I used to be depressed because of what he did, I had nightmares and I couldn’t focus in school anymore. Now I’m finally moving on with my life, I exercise, I get good grades and I finally accepted myself and partially healed from what he did to me. I’m in a good place!! I’m me again!!! And he’s finally feeling some consequences for his actions, I’m not the only one suffering anymore. He terrorised me for months, now he feels at least a small amount of the pain I felt. I’m aware I shouldn’t indulge in this feeling, because I don’t want to be a vengeful or hateful person and me being unaffected would be sign that I’m finally healed, but I’m not there yet.
