He told me to piss off, what now?

He asked if he could phone me and update me on something so I replied with "ok :) by the way I legit thought you said you're about to run into a door" I read his message quickly and it said he was about to run out the door.

Next morning I got woken up by 18 messages calling me an entitled princess, telling me he's pissed off with everything including me so "piss off and leave me alone".

So I told him that he doesn't need to visit now (long distance) that I'm disgusted by how he acted because I did nothing to deserve it and that I will indeed piss off and leave him alone.

And that was it, no response, no apologies, no explanation for his outburst.

What are my next steps, I feel that I fully deserve an apology at least.
