Realizing my ex is manipulative

I broke up with my ex 2 months ago. It was a hard decision but I’m glad I made it. I’m feeling a little off today because after I blocked him on social media for my own healing he texted me today. He asked if I blocked him and told me he had covid. Why he felt I needed to know? I don’t have any idea. The easiest thing for me this breakup has been just forgetting he even exists and trying to remind myself that there is more life to live and more people to meet. In our conversation (which I didn’t want to have) he asked how I was, asked about my old friends etc. I guess when he realized I was completely uninterested and not missing him and after I had ended the conversation he sent a message a few minutes later telling me he was “talking to someone new and he thought he’d let me know” tf?! I told him that I really didn’t care to know that information and that whoever he was talking to probably wouldn’t appreciate him messaging me and asking how I was. The conversation basically ended after that. But he said something like “should I have told you that? Are exes supposed to tell each other those kinds of things?” I’m just like wtf dude. Well flash back to a few weeks after the breakup he was really pissed I broke up with him. He told me I had no friends, his friends hated me now, and my parents didn’t care about my feelings. His family acts the exact same way which is exactly why I broke up with him. These were my exact worries. Just let’s me know I did the right thing. I just wish he’d leave me alone and understand that I really don’t want to hear about his life..not even in a mean way..we’re just not together anymore. Ugh.
