Oh that sounds so terribly painful! I would be furious, hurt, betrayed and upset.No, it is NOT your job to keep the roles straight, it was theirs and Teacher T
I guess screwed it up. Not your fault, I think, for your own sake, you need to express to both of them how you feel. And receive an apology from both of them. If it were me I'd probably revoke the consent to discuss myself at this point. I think that they should have spoken to you first, before speaking to eachother, just my opinion but I think sometimes we put too much trust into the 'system' that everyone knows what they are doing. In the end, sometimes we have to take some of that control back. I'm sorry this happened to you and try to really express yourself tomorrow. It's ok to be angry and I'm sure you'll sort it out with both of them.
