Welcome to sr, Crownlink. Lots of information and experience here.
My husband didn't like me drinking and I tried to hide it but they know just after one drink he could tell.
Your girlfriend probably does too, but heed what 1newcreation says, if anyone knows you well at work they may suspect, forgetting all about the dangers etc, you could lose your job, then it may be your girlfriend.
Stick with us, stop now before that slope gets very slippery. All the best.
