Ghosted my abuser - confused

I ghosted my situationship a few days ago. I know ghosting is generally shitty and immature to most, but I think it was fine in this situation - he was really controlling and verbally/psychologically/sexually abusive. Towards the end, he would barely talk to me, was always going back and forth on if he wanted to talk to me anymore, and made me feel like I was just bothering him. So I stopped. I deleted him on everything. But he still just keeps texting me. Texted me the first night I deleted him and he asked me if I was okay. Then tried to say Goodmorning. Then sent a question mark. And then this morning said “you haven’t texted me back in like 2 days. Is everything ok?” I don’t get it. Before I deleted him off social media, he barely wanted to talk, acted like every little thing I did annoyed him, and he would express being unsure of talking to me at all anymore. So why does he care so much all of a sudden now that I decided to be done? I thought he would be happy that I left him alone.
