Well, my wife hates piano, classical music, practicing, and has "sensitive ears" as well. So yeah, it does restrict my practice and recording sessions quite a bit. I wait for her to go out on errands, then get every second of practice time I can out of that time slot. I truly envy guys (or women) who can just walk over to their pianos and practice or play whenever they feel like it. And they probably take that freedom for granted.
When one is young and in love, it's important to assess shared interests, and interests that are not so shared. If one of the latter involves your passion for piano, then that should become a serious issue for further discussion and consideration before things get much further along in the relationship. I never realized just how paramount a shared taste in music can be. Classical and Rock just don't mix well, for example.
Unfortunately, it's not as simple as trying to meet a hot conservatory piano performance chick (or guy). Then you might end up fighting over the piano and practice schedules!

If you want to hear the latest result of my crazy one-hour-here, two-hours-there practice syndrome, check out my latest recording of Bortkiewicz's Prelude, Op. 33, No. 7 in the Audition Room. I will say that I have learned to practice with deep concentration and the greatest efficiency, making every minute count.
