My T said that it was ok for me to text him, but he has stopped responding to my txts and I will no longer do that. I don't have his email address and he is not available by phone except in emergencies - which I have never had.

I think it is good for me. It teaches me not to expect his support, since that is not something I will have for very long. At least I think that's his rationale. I am not going to ask him about it.
