With regard to proactivity: I agree that you would not actually propose stuff to her. But you could cultivate her proactivity by encouraging her when she speaks about it, even if right now what she is proactive about isn't rewarding to discuss.

Right, I was thinking more about her work than her taste. What bothers you when you listen to hear speak about her work?

About ignoring everything you don't like: it sounds like taking a few walks would be very helpful! What happens if you propose changes of subject?
