Take heart, she doesn't feel she needs to smother you with compliments, probably because she thinks highly of your playing. She could let things go and then use the catch all phrase ' You're very musical'. I had a teacher like yours, and it was very hard. I found over time that in fact he did support me in ways that weren't so obvious in a lesson, like, encouraging me to join performance groups, etc.... but I never felt like I was worth much as a pianist and that was always, always hard.
He would say 'you're not paying me to have me tell you what's good' and I would argue that I didn't have a clue what was good because he never told me. I assumed everything sucked. One time he said 'I think you are a better pianist than I let on', but that didn't help much. But, with this kind of teacher, when they say something nice, you know they mean it. That teacher died, and with subsequent teachers, when they say something good - I have a hard time feeling that they are not just trying to make me feel good, just like I do for my students! But it is basic human nature, after all, to need encouragement, and it does help for instance, to know when you 'get' something.
So, after all that rambling, perhaps what I mean to say is - you have to decide, can your ego stand up to this? Is it worth it for what you are getting from her? Or would you be happier with a teacher who you found more encouraging? Some people just need more than others. Which are you?
