Testing is a common thing in therapy. We want to see if they really mean they aren't going to reject us. It's the same things that kids and teens do to their parents (and the reason that kids often behave the worst around their parents and then are fine, say, at school).

I know I definitely have done some testing of my marriage counselor, for whom I have some paternal but also some erotic transference. He's said, like your T, that he wasn't going to reject me, that nothing I said or did would make him leave. I certainly tested with some of that, from sharing about the transference earlier this year, to a couple months later admitting that I loved him. And he hasn't gone anywhere (though there was a misunderstanding involving boundaries that made me worry that he was--that's all been resolved now). So your T probably wouldn't be surprised that you were testing her in some way (and it sounds like she's passed so far!)
