Thank you, people, there's some really heartening content appearing.
A further interesting development.
Two days' nastiness, including the evening sandwiched between. Wifey's panicking because she thinks local people will find out about her alcoholism. I think I've found the Achilles heel.
In our exchanges, I stated...
You are a choleric drunk - she thought I was referring to cholera, not anger.
I don't want to know you when you're drunk - I'd rather be downstairs, working.
You are immensely unpleasant when drunk.
...and more along these lines.
Apart from the usual 'attack is the best form of defence' stuff, I got the 'splitting up' speech, the 'it's all your fault' speech, the 'you're a liar' speech.
BUT
At no point did she deny being a drunk or an alcoholic.
I've since agreed to pick her and useless SD up on Friday night - they're making their own way to the restaurant.
I also got a credit card holder hurled across the room. I simply thought, 'act your age and not your shoe size'.
Now we'll see...
