I'm going to go a little against the grain and say that I think he handled it as best as he could. He might have overreacted a bit, but I believe he did it because he cared. Since it was only your second session he doesn't know you all that well. He can't tell yet if he can trust you that you are going to be OK. I'm glad that he protected you, even though he probably knew that you might end up angry at him. I think you found a good one.
