Hi there,

The setup where your T's wife is your boss doesn't sound good at all. Whether he breached confidentiality or not, the fact that you think he might have shows that you don't seem to be very comfortable with this situation. Did you agree with this T at the beginning how he is to contact you if he needs to (email, phone number)?
Did he offer to rearrange or just cancel completely?
Two months off in a year sounds like a lot of vacation. Lucky man, if it was all vacation and not some long-term illness... But he is not necessarily the T you want to stick with long term, from the sound of it.
