Hey KaylaNicole,
Yeah, it does sound like she cares about you a lot, after 12 years, I would say there is definitely an actual relationship running along side by side with the therapy. It can be really hard to untangle what we are feeling in therapy, if it's really about the therapist or about something in the past that we needed to get but didn't.
Maybe it's time to talk about all these issues with her. You laid them out really clearly here

and from what she said maybe she is able to talk about them too.
