Well, my girlfriend doesn't like much outside of one-hit soundtracks and Elton John. It's pretty difficult to get in my jazz time, so I try to listen to it during the day while I study. That said, not everyone has the luxury of having as much time as I do. Thus, I would either set up your stereo in a separate room and designate specific times of the night as "Jazz listening" times, OR I would buy a discman and listen to jazz on the way to work (or even at work? Some companies let this fly).
