I'm sorry you have to go through that... it's certainly confusing!

As I was reading about MT, I told myself well, if he lies like that to his clients, going as far as writting an automatic response that was untrue, it's probably better you stop seeing him; he doesn't seem trustworthy at all! But I understand the hurt and the disappointment and sadness...

And MT is the only one responsible for what happenned; he is the "bad" one IMO, not your current t; current t perhaps didn't even know what was really going on with MT at the time or thought (rightly or not) that telling you would make things worst... That being said, I know how hard those feeling are and hope you're going to find a way out of this and, like you said, find the courage to discuss it with your t...

Take care
