for those with therapists- how do they treat you with your disorder?

hi everyone! i'm not new to this disorder or subreddit by any means, but just wanted to let you all know i'm writing this from a new account since i deleted the last. quick question though- for those of you with therapists, how do they treat you and handle your separate alters?

i have recently got a new therapist and yesterday was my second session with her, but i'm having mixed feelings. i've never had a therapist be so open about the disorder, most in the past have swept it under the rug or ignored it entirely but this new one hasn't and it's a little jarring, i think? i was talking yesterday about my traumatized little parts and she was quick to say it'd be unethical for her to speak to them since she's an adult therapist which i thought was strange. i'm still an adult, and they're not real children i'm bringing with me, just another part of me. i want to say she is not a DID specialist, she's a person-centred therapist that i've been given by a charity and i feel mixed about her.

at the end of our session she said she would see me (or maybe not me) next week and it did make me laugh but i'm just like... how do DID therapists treat those with the disorder and is she right or am i just surprised by her openness? she has been good at asking questions so far but i think i'm just like... don't perceive me.
