Help!! new years with girlfriend!!?

so, my girlfriend of a year and some change and i are spending new years together, but have a little different idea of what to do for it... she wants to spend it with her friends, which is what we did last year, and it was awful, because i don't really drink but her and her friends do. and i want to just spend it with her, but there's no way of doing that, so i accepted that i would have to spend it with her and her shitty drunkard friends. anyways, i atleast tried to bring a friend, to make it less of a hellish night, and she said no because it would be awkward and terrible because my friends hate her friends. so now i have to spend it with her and her stupid friends if i want to spend it with her at all. what do i do???
