It would likely be more useful to you to move forward and find a new T. Staying stuck and hoping for something that will probably never happen is wasting your time and energy. I dont know your story, and I'm not asking to hear about it, however it sounds like you are waiting for someone who has made a decision to leave and not come back. There is more than 1good T around, feel your way around and open up for options. The past is always better left in the past. If your past T wanted to invest themselves in you they would still be here today. Let go and I bet a great T will be waiting for you to find them. Good luck.
