It's hard for me to be rational about the pros and cons of seeking and getting gratification from a T. I thought the best thing that ever happened to me in all of my years of therapy was my current T allowing me to hold her hand. Even if that was gratification, and maybe was unhealthy, I think it DID help fulfill some need inside of me, and at the least, got me to realize what is lacking in my RL.

I do think it's important to tell your T about your feelings for her before your therapy ends. Go with your gut feeling and do it!
