Uh, I would get another demo. But since she gets her feelings hurt easily, I would do the cowardly thing and just um... hide it from her, that I got another demo. I'm not good at this social stuff. But I would not want the extra and unnecessary frustration in my life. Though I guess hiding something like that from her would cause me stress as well.
It occurred to me that it would be possible to tell her to tell you stuff more often, but that's too much like trying to change her... that kind of stuff is too exhausting for me.
I guess it would come down to what would cause you more unpleasantness: frustration of her not-very-good communication, or worrying about her feelings over a new demo.
