I have/had this same problem and my current T has no issue hearing me talk about my old T and how much I liked working with her and how hard leaving her was. Last week we spent almost the entire session discussing her and how I can get over her. I know what you mean about not finding someone like her. I am on my 3rd therapist since I moved. I also discussed that therapist a lot with those 2 and they didn't seem bothered. I am just now starting to get comfortable and trust my current one and let go of my ex one after our last session almost 10 months ago. My issue was definte transfernce plus I moved out of state.

It does get easier it just takes time.
