i'm sorry you're still having a difficult time with your agf. one burning question i would have would be
why are you drinking with this addict?
my xabf is on methadone maintenance. in the early stages of the program, after he got to take home three days' worth at one time, he would sometimes dip into the next day's dose. from what i hear this is somewhat common. it is hard to do a turnaround - they are used to being in an altered state, and they WANT to be in an altered state. it's something they have to come to terms with, and realize that it is sabotage. it took mine a few months to just do the program the way he's supposed to.
your girlfriend wants to be high, plain and simple. even if she didn't take extra suboxone, she is still getting high. is she in recovery? not even close.
you know the truth. what are you going to do, after you get up in her face yet another time?
