Why is he ignoring me? Did I screw it up for myself?

So we were pretty much getting along last night but today it went downhill. After having a good talk last night, we spoke this morning and he randomly asked me if I was playing him twice. He then asked me did I have him on my agenda and I said no. I said it in a way like I was joking but sometimes he can never take a joke. A few days ago I made a joke like I forgot his name but he took it serious and blocked me. He shortly unblocked me and we made up. It’s back to where it started and now he’s ignoring me. After the agenda thing he hung up and blocked me.
