My wifes dad is an alcoholic, so that was the issue. But I told her it wasnt fair for me to have to pay for his mistakes in life.[\quote]
This could be another issue, is anyone an alcoholic in any of your families?
My roommate 2 years ago was NEVER allowed to drink. If he drank his girlfriend would lock herself in a room and cry, over one beer. Issues she needed to deal with that affected him.
Regardless of all of this, take a moment and see why she's asking you to cut back, what are you doing that's wrong in her eyes and why?
Lastly, 5 gallons lasting 3 months is a good thing, are you really concerned about having beer sit around for 3 months!? This is delicious homebrew, not piss water. My SWMBO's Brother in Law brews and he talks to me all the time about it. He's terrible at it, thinks hes fantastic, and brags about how he can finish a batch in 2 weeks. Is that really something that sounds good to you?
