What initially made me trust my T is that she stuck it out with me through our really rough beginning. She was forced to be the middleman btwn me and ex-T since ex-T refused to communicate with me directly. So it kinda made my T the "bad guy". We also had a difficult time with her boundaries: some were too loose and some too tight. But she worked through it all with me. She put up with ex-T's b.s. and she stayed constant and strong for me. And for that, I gave her my trust which was very valuable considering what ex-T did.
