I don't get this bit sorry...
We had 6 bottles of wine between 5 and half bottles between 5 of us...
'6 bottles of wine between 5' and 'half bottles between us...' Struggling to make sense of that.
Anyway in answer to your question, 6 bottles between 5 people (if that IS what you meant,) sounds about right for a night out. 3 glasses each roughly, with a couple of people having 4 glasses? Not too much IMO.
Also, like some teetotallers (not all) your friend sounds like a judgemental bore. I know a couple of teetotallers and they always have something to say about ANYone who has a drink. In addition, they are boring and snarky and make it obvious that they actually want to drink alcohol - and are just projecting.
I don't think your friend is jealous - as a pp said - but she is boring and judgemental.
A friend of mine is married to a man who doesn't drink, and she can just drink a solitary glass of wine, and he starts barking 'piss-head' and 'lush' and 'alkie.'
It's got to the point now where she won't drink in front of him now, and won't have alcohol in the house. She just goes to a friend's house to drink. OR goes to the pub with her sister or one of her mates. I couldn't live like that personally. I would find it very hard to live with a man who doesn't drink alcohol. I don't think a teetotaller and a drinker are compatible long-term tbh.
