The crack about lying would bug me because of his making a comparison where there was none. Your first therapist said he wouldn't see you if you saw another one at the same time, but this one didn't put any sort of condition on it so there was no question of having to withhold information. Besides, you told him up front about the first one. The issue of lying or not lying to him isn't even relevant. So maybe he's trying to be funny...but it comes across as insincere? I find that a lot of problems or concerns I have with other people comes from having really different ways of communicating.
