What was his response? I'm telling you seriously, and I don't think many people believe this. When your T said what he said, I don't know what his intentions were, maybe to help you, or maybe to help himself, but know this:
As I said, your T had engaged your attachment system and pushed it into high gear. You are not just a normal person with no issues who out of the blue decides to cross a boundary and text. Realize you are dealing with the compulsiveness (these are my words, my descriptions), with having your attachment system activated, this compels you (like you can't stop yourself), to make sure everything between you and the person you are attached to are secure. The more your therapist pushes you away, the more intense it is going to get. I'm telling you this because I don't want you to feel any shame/guilt; because you are being compelled to be reassured that the relationship isn't over, when your T kind of layed it on the line.
