I went back to read your first post on this. You are probably right that she is bringing things out in you that need to be resolved, but from what you've described (her talking too much and challenging) it could be that she is not skilled enough to see what's going on as something to work on. Dismissing it as having to do with summer break sounds a little lazy to me, or uninformed. And yet, you have an attachment to her, and that makes it hard because part of you knows there's something being activated here that needs looking at; and yet, she just doesn't sound all that with it.

Were you able to tell her how you respond to her challenges and excessive talking? If not, that would be a good first step. She should care, first and foremost, that she's being effective. There are lots of ways to work with an individual; and if she's not willing to readjust, then yes, I would definitely look for another therapist.

It's good to compare styles and approaches (not easy though, when you have an attachment to one already). Otherwise, you just can't know for sure. And it doesn't sound as though this therapist sees the opportunity here to dig deeper.

Good luck. This is hard stuff, but you're asking the right questions.
