DH has a bad relationship with alcohol.
We've had lots of arguments over the last 6 years about it. It's starts that he says he doesn't have a problem, it's normal, he can stop and usually ends with him staying at his parents for a few days.
The last time this happened was two weeks ago and we agreed that neither of us would drink AT ALL unless we had no DC at home/were away with without them.
The time before that was at the start of the year, when he suddenly decided he's bipolar and depressed. Having dealt with MH issues myself for the best part of 20 years, I don't think this is the case.
He is not actively seeking help for either the MH issues or the alcohol (you know, because he doesn't have a problem.)
So this week he bought a bottle of something 11% ish that you dilute with tonic and had a couple of glasses without mentioning it to me. I saw the bottle the next day and asked him about it.
He said "oh it's just a mixer" - it's obviously not. Was he gaslighting? Trying to pull the wool over my eyes?
Later on he changed his tune and said that he meant you mix it with something to dilute it. So it's not like having a "proper" drink, he didn't even see it as having an alcoholic drink even though the amount of it he drank adds up to "proper" drink.
In my mind, what he drank is the same as him having a beer or two.
Anyway, point of the post. Is he ever going to change? I can't carry on having this same argument every 6 weeks. I'm exhausted and he isn't safe to parent when he has had too much to drink. I constantly have to be on high alert 24/7.
TLDR: DH is a functioning alcoholic and won't admit it. I cba anymore. What do I do?
