I could live with that too. (I sort of do)
My GF has about 1 beer per week. Doesn't bug me at all.
If/when we live together, I may allow her to have alcohol in the house, as long as we can have a rule that I get to dump it if it "calls" to me.
Other people can drink, I can't. It makes me "sick." I have an "alergy." I accept it as a fact of life.
I didn't give anything up, though, I choose not to drink. (Alergy) That mindset helps me.
After some time, when you hang with some annoying drunks and see all the drama and crap they put themselves through, that evening and possibly the following day, I predict your "jealousy" will go far away and you'll have JOMO. (Joy of Missing Out)
All the best,
CJ.
