That really is fantastic news, make the most of it, as I found it really helpful. At the same time though, it's worth having a plan B, so have all docs ready to grab, nappy bag always packed, and if you can create a nest egg that only you have access to it is very worth doing. if the worst ever happened then you wouldn't be caught by surprise. Might be worth lodging your folder of documents with a friend if you have anyone close enough to trust.
One thing I learnt is that you can lodge a record of dv that is just that, and is then just on record in case you ever need evidence. I so wish I'd known that, I'd have had him done for stabbing me while drunk, and for what he did to dd1 after we'd left, whereas it was dropped due to insignificant evidence.
Other than that I really echo SS's advice, don't hang around waiting for him to decide whether he's choosing family or booze that day, just carry on. Day out? Just go. Once they twig, they'll up the stake though, be warned. But by changing the way you react to their behaviour you get to step back and reassess.
Some one new, sorry, I can't remember who, described wishing their dp would die- I used to have those fantasies, and other times I could see that when it happened I would be the one nursing him, and how I used to cringe at that thought. That's not living.
Somewhere further up there is a link on detachment, I'm not sure where, but it's there several times! Anyway the jist is you care about, not for. So if he passes out on the sofa, what would you do if it was a flatmate? then you do just that. Really tricky, esp when stuck in the madness, but so worth trying. Just remember that atm you are trapped by the illness as much as they are, and if they can sense you are withdrawing your enabling they'll up the game, in a similar way to an abuser.
Thank you for your insight Hopefully, I'm sorry your doctor was so unsympathetic. I've found judges can also be like that- although my sol suggested with a wicked grin that xh's alcohol consumption was probably similar to what a district judge consumes in a day 
Ds has finally calmed down and has just been sent to bed ( he was facing the wall as he was rocking on the time out chair) Wishing all you lovely ladies peace, and inner strength.
