Maybe he doesn’t want to ruin the tone of your relationship. He wants to keep it strict and disciplined. Sometimes the drunken shenanigans just aren’t someone’s thing. I don’t think there’s enough info on either side to be assuming much about either of you. If I were you I would try to think of a punishment that dealt with the specific thing you did wrong. Maybe stop drinking for a small period of time or try harder to not call them when you’re drinking. Or every time you drink a beverage you owe him a pic or something you snuck away to provide. There are options and it’s unlikely that it’s ruined forever. If this one event stops everything then he’s either too strict or your drunken rant was more than you’re telling. Some people have had bad experience with drunk people ( fighting , cursing, assaults, etc ) so maybe one day you can ask him to specify if it’s something more. I worked as a bartender for ten years and just got tired of the stupid drunk drama so now I avoid it at all costs in my older age.
