My husband still drinks but he is very sensitive to my feelings. If we go out together for dinner, he will drink water with me. He loves chocolate, so it kind of resonated with him that for me to sit directly opposite him ploughing through a box of chocolates and he couldnt have one would not be a caring thing to do.
He will have a glass or two at home but I can be occupied with other things, it doesnt bother me that much.
You say your GF's drinking is moderate, to be honest it doesn't sound very moderate to me.
Look only you know the answer to this deep down but I don't see any harm in talking to your GF and telling her how her drinking right now makes you feel whilst you are in early recovery and is there a compromise that can be made?
Besides I believe the best relationships are alll about compromise and being prepared to walk in your partner's shoes on occasion.
Just my pennyworth
