Bf disappears when he’s drunk

My long distance bf is Puerto Rican (living in the US now) and he says in his culture drinking is a big thing. And yes he’s a big drinker. He drinking less since we started dating (10months) but he goes out once in a while with friends to drink and I’m completely fine with that. The problem is he gets too drunk and falls asleep somewhere or don’t check his phone. He’s good with staying in contact the whole time until the end. I told him I’d prefer if he just lets me know when they’re moving spots or when he’s going home but he basically live-streams the whole thing but disappears later so I don’t know if he got back or he found a place to stay. Right now I’m up waiting for him to wake up and check his phone because he is gone again and because of time difference, he might wake up when it’s midnight here. I told him as he was drinking that he is too drunk and he should slow down but he never listens and says he’s good. At least he was at his co workers place for a party so I know he’s probably sleeping there. There were a bunch of girls but I just gotta trust him to not fuck me over, nothing else I can do at this point🤷🏻‍♀️...

how do y’all deal with drunk significant other? My ex husband didn’t really drink so I never had this problem but this dude tires me out even tho he’s the one going out😅 I honestly don’t like how he turns when he’s drunk and I told him but he thinks he can handle his liquor. I’m tired man.
