My alchohol counsellor told me that but then I lied about my drinking because he took details of my kids and because I lie about my drinking incase any one endangers my relationship with it.
One ex actually got me a sponsor so I left him after all could not endanger my love of alcohol. If She wants to drink she will drink and it may be a few weeks before it spirals out of control may be sooner depends but until that time she will convince herself she can drink in moderation. Good luck and wish I could give you some good advice
