If you keep saying or asking if you are needy and demanding, you are indicating that you aren't really trusting her answer, so I suspect she's changing her approach to "since you seem not to trust my answer and apparently need more proof, we'll have to investigate your fear about this and see if you really are needy and demanding, and if you are right in your own assessment of yourself, we'll see what we can do to change that since you are not comfortable with being perceived that way". Continuing to ask the question means you aren't trusting/understanding/internalizing her response, so she has to change her approach rather than you just continuing, apparently stuck in that spot. That doesn't mean she doesn't like you; that means she is trying to help you find a way to move forward.
