Sounds like you were deliberately provoking your buddy's g/f, which is kinda immature on its own. It's his problem, anyway - not yours, and not the problem of anyone else here, really. I can recall very, very few people around here who have had truly UNsupporting significant others; they don't all like beer, but they let us do our thing, and most of them make some effort to be supportive. My wife drinks my beer, doesn't mind me talking about it SOMETIMES, lets me put on the Jamil Show on long drives, loves it when I bring beer to show off at parties, and likes going to new pubs with me (even if I can't get her to drink an IPA).
She's not going to start posting here anytime soon, but she doens't mind that I do.
I tend to think my experience is MUCH more common than that you describe.
