How long it takes for guys to acknowledge they did a mistake or they Don't admit at all?

I went into a stupid fight with my boyfriend. We were going out in public for dinner and we were joking about sth. And i hit him on his arm in a cute way , he took it way too serious and said nooo don't you ever dare to joke with me like that again and that if it happened again there would be bad consequences.

I said relax you just say don't joke again like that and thats it no need for such sayings. And he left and walk away. I called him no answer i recalled and no answer again and went home.

I did text him told him i am leaving not coming back ever and it has been two days and no contact all.

He hurt me with what he said and i am not going to call him or try to apologise for sth i didn't do.

My question is would he realise that he actually made a mistake and its his fault. Or he will keep thinking that its my mistake

Please no hate comments its just a question
