for me it's been how he responds to issues. i was probably naive when i first went to therapy. i was so broken and i wanted so badly to get better so i was like 'i'm going to be honest!' i realize now how dangerous that can be (with ts that abuse their authority) tho thank goodness my t is not that kind of t. now that i'm older and wiser six years later, i realize i trust him because he has demonstrated over time that he will respond skillfully to my problems.
