My bf is the best guy in the world BUT HE CANNOT HANDLE HIS BOOZE

[FilmaWlintstone]

I don't know what to do or say really

We we currently in a cab home

He's perfect in every other way but he cannot handle his drink. He's never abusive or horrible with it he just falls off a cliff and becomes very drunk very quickly

Aibu ??? I feel like a sort of parent when I'm out with him - he's not like this in any other way he's wonderful - he just doesn't know his limit

I think I want to get married and have babies one day with him I don't want to ruin it

I feel I'm being unreasonable ???

Urgh, I'm 33 and I have low tolerance for alcohol. But I have had that for the past ten years and I have learnt my limits. I can listen to my body telling me not to drink more.
Sloppy drunks are disgusting and embarrassing, as his age there is now excuse. He's been legally allowed to drink for almost half his life and he should have been able to work out his limits by now.
I'm not convinced he will care/stop unless he has a very nasty consequence as a result but obviously that's not something that you hope for.
Have you ever brought this up with him?

Now = no

My DP's exactly the same OP. It's the only thing we argue about. He becomes sort of non existent when he's drunk and I hate it. I try to avoid most events/nights out with him because I'm embarrassed.
When he knows he's going to be drinking he has "practice beers" at home, but it never makes a difference.
Once he reaches a certain stage that's it, his eyes go wonky, his speech is slurred, he's clumsy, there's no eye contact etc.
He knows how I feel about if, yet still feels like he should be keeping up with his friends. It's very frustrating but it's his only downfall so I've accepted it because he's so lovely when he doesn't drink!
