Sure, she may make it up there, but at some point she will drink. In my case, her drinking was taking place IN THE CAR as she was leaving the parents house.
The point of all of that is to focus on yourself right now. Do what you want to do. There may be a chance that he will come back and blame you. (i.e. - You told his parents so they gave him grief about his drinking, so that "made" him drink) You CANNOT cause him to drink.
ellima01 gave excellent advice: if you need to, slow it down to one hour at a time. Heck, if it gets that bad, slow it down to one minute at a time. Whatever it takes for you to feel success that you survived that time period. There's a lot more minutes in a day than days in a day...so there's many more chances for successes
