This sounds exactly like the relationship I had with my T a year a year ago. It has only escalated since. I'm not sure how old you are (not that it matters) but I'm 18 and my transference is kind of fresh for maternal and I think my T also struggles with counter transference as her kids are my age. It got to the point where I ended up in the hospital because I couldn't leave her room, I was so terrified she was going to leave me like my mom.
I was in the same situation as you, thinking is it healthy for me to stay in therapy or not? And indeed it is! Your therapist even though isn't talking much about it is trying to figure out a strategy. For my relationship with my therapist, it took us over a year to figure out a way to work with it. Basically, she has accepted the fact I want her as a mom and I'm allowed to treat her as a mom, I'm allowed to hug her, I have a blanket that she gave me (I know that's a lot) but...she keeps her therapeutic boundaries that even though I push and get angry like a kid would I will and have learned that I have to become the mother in myself because she won't always be there for me.
