My T has constantly told me in the past that I can see him even when I feel better and 'dont need him anymore'.

If you develop a really good relationship with a T, I don't see a reason to ever completely cut them off from your life(especially if they've been a big part of it)

You should talk to your T about this... when I did he was very helpful and made me feel that my future was safe if I wanted to see him forever but he says people change and I may want to leave therapy one day and never come back.
