Funny how that works when it comes down to the actual conversation and the other person gets to respond with his/her own thoughts.

I think you and T have more to talk about. Yes, good idea to ask him why he thinks you should continue. My guess is that he does appreciate the strides you've made and sees room for more growth. He may think you are avoiding something and would like to see you continue for that reason. Deeper and more meaningful changes may be available and you could miss out on thtat.
