As for the drinking, everyone else has good advice on that. Tell her you don't drink or don't want to drink. If you don't care, then try some (advice, beer tastes like what I think pee would. Stick with liquor). The thing is, just don't drink much or just take some little sips when she is looking or something. The drinking isn't to much of a big deal, you can get around that pretty easily (unless you give into the peer pessure or you decide you do want to drink).As for the GF and this girl thing, no one can really help you with that. In fact, this whole situation comes down to your morales and what you think is right. The right answer here (if that is what you are asking for) is to do what you think you should do, not what you think you want to do. But I am not that good at giving advice, except for the beer thing. It does taste like what pee most likely tastes like.
