wow. Grrrr! Can't stop shaking my head over this. Yikes, how awful.

you know, it is possible that the new job fell through at last minute, or maybe before starting MT found out something about that made him decide not to -

I can think of some scenarios to explain him I guess - but (I am very sorry to say) not for yr T, if he knew the facts & didn't tell you, especially since he was the one helping you handle MT's sudden termination. I can only speak for myself but that would be a deal breaker.

from where I stand, your cancelling this appt to give yourself time to breathe and process this information shows a lot of maturity, LIT. I think you're doing very well, this has got to be immensely hard ! ! !
