"if we were to meet in a cafe then it would end up us going to off licence and buying wine to take back to her house."
That will only "end up" happening if you walk to an off-licence, put wine on the counter, take your purse out of your bag, take your card out of your purse, give the shopkeeper your card, type in your PIN, put the wine in a bag, leave the shop, walk back to her house, go into the house, and drink the wine.
These things DON'T "just happen" - YOU DO THEM!
I used to feel like there was an electro-magnet in pubs and every time I walked past it latched onto the keys in my pocket and dragged me in.
Because I was a drunk.
These days I am still an alcoholic but I am no drunk and the magnet no longer works. In fact, now I think about it, it must be located in the Stella pump, because even when I do go into pubs these days, I stay and then leave without buying or drinking any alcohol.
FWIW ALL my meetings with friends used to end up in pubs or bars - but I have only had to drop one friend as a result of stopping drinking. Because he is an alcoholic.
In fact, that's not even true. I haven't dropped ANY friends.
But a couple have dropped me. Because I can no longer be relied on to drink pint after pint of ale in dark barrooms while the world carries on outside.
all my other friends are happy to be with me because we now go to a wider variety of places together.
(Those are the non-drunks, obviously.)
