I know what your T is doing is unprofessional and wrong, but it's time to move on. I really strongly suggest that you see another T so that you can work though what went on with previous T, and whatever else you were working on in therapy. It's very hard to go though something like this and you should have council.

Also I'm a little unclear on what it is you are hoping to get out of Emailing old T. Do you want referrals, are you trying to make your feelings known. Are you trying to work though what happened in the relationship?
