OH has no stop button when he drinks. He thinks he's still 20 but he's 50 and when he drinks he gets shitfaced and he can't handle it. He won't see that he drinks too much and disagrees that he can't handle it even when he throws up and feels awful the next day.
AIBU to want to tell him / ask him to drink less /stay in control or at least not get rat arsed every time??
I don't want to tell him what to do, it's his life but it's affecting mine and it'll affect his health. We don't live together but plan to in a few years.
