We still struggle with trusting T and have been seeing him for almost 2 years now. We also still test him to make sure he is trust worthy. He seems to know when we are testing him and he understands why we do it.

Can you tell your T that there is still a part that does not trust her fully? Maybe that would be a good way to bring it up and out into the open so you, your T, and your un-trusting part can work on ways to start building that trust.
