my two cents.... my very last T(of 4 years) disclosed just about "everything"... the last few months of therapy were done in an office in her home... on one hand it was good to relate to someone that had gone thru many experiences such as myself... on the other hand, the fact that I knew so much about her made it much easier for me to manipulate therapy - so in the end, disclosure doesn't work for me...
knowing who she was dating, how her husband passed, that she had had an eating disorder, that she was adopted, that she had a major depression and didn't work for 5 years, that she was taking classes out of state, which T friend she had lunch with, that she didn't have a good relationship with her adult son, that her youngest son was going on a special school thing for the summer... Yaza.. I could go on... was too much for my already crowded mind..

This new T discloses nothing - and I asked that he not - I just don't want to know...
Oh, I know where he went on vacation... but not about his personal life.
