I think a T relationship is just like any relationship - the 'feelings' come and go. Have you talked to your T about the change in the relationship? If you don't feel you can work it out, I agree that you need to move on. Perhaps a new T would give you a new energy to get your therapy moving again. However, 5 years is a long time and there is a lot of history there. I would make sure you think twice before giving up on the relationship. Good luck.
