About 7 months ago, I was in a place where I was struggling with therapy and my thoughts about it - more than any of my "issues". My therapist (who was fairly new at that point) told me that rather than terminate, I was certainly "allowed" to take a break - she would be there when I was ready. I took a one month break and it was really good for me. In the end, it helped me determine that she wasn't the therapist I needed and that I was in control of what I wanted to achieve in therapy and how to best define that.

I guess what I'm trying to say is, rather than just fade away...maybe consider telling her you are taking a break to assess what your goals are and whether or not she is the best therapist for you to reach those goals. I think that will help with you understanding that you really are in control of the process and also let her know that you aren't just "ghosting" (which will also help you).
