He didn't answer nor return my call. When should I reach out?

On Monday I irritated him for being annoying and he was fed up.

On Wednesday I asked him if he is still mad and he approved. I asked "you are not talking to me for how long" . He said "till you learn and till I'm no longer pissed".

But later that night I don't know what happened, but I got extremely anxious and wanted to get in touch. I messaged him on Viber because I saw him online. He usually responds immediately but now... I was left on delivered. Then sent him a few more texts. After 10 min of no response... called him. His phone was ringing without him picking up. Usually if he doesn't want to call, he declines, but not this time.

I got worried... wrote him another message to beg him to call. He didn't respond and finally texted him "if you don't want to talk, please say it, but don't do that to me... I know I'm wrong".

Again left on delivered. He opened to read the messages the next morning and left me in seen (yesterday).

I'm super anxious, should I reach out to him or just wait?
