Education is not a bad thing. It's why therapists have continuing education classes. L is always reading, listening to podcasts, consulting with fellow therapists, taking her classes. She is also in her own therapy. These are positive things. So her wanting to educate herself more on SH is a good thing.

Still, I don't think this therapist is good for you. The fact that you keep providing her with things, often paid things and she accepts them, that she is extremely inconsistent to the point of harming you, that she discloses more information than what is helpful to you, etc.
