Sigh. This works against your progress and is a constant distraction (for you and for them)... I came in to the middle of your story and certainly won't ask you to repeat it as I have gotten the general points of it (and feel bad you are stuck in such terrible circumstances.)
I don't remember though, do you
HAVE to see T2 or can you switch her out for a new and improved model? I know you love T1 and are trying to work on closure...being told you should be angry with her, which is your decison to make, who you are angry with and when (a T tried the exact same thing on me before because she disliked my ex-T's actions, and it didn't work because I wasn't angry with him; there wasn't anything to be angry at him about re: what SHE didn't like. Those were
her own issues.). Being manipulated like that leads to more pain and resentment when what you need is support.

(And I am sorry, I don't think I answered your question at all, perhaps because it brings up emotional issues for me as well.)
