They are allowed to break confidentiality if your safety is involved. Some react more strongly than others. I had one who overreacted so I was called in a few times. Mind you I had already done something but was not seriously suicidal. But I really didn't like it. When I switched shrinks, I made sure that it was clear that I didn't want him to ever do that without a discussion of what it would be like for me. I haven't had to worry about but I haven't really been thinking that way for a while now. Good luck. Best to get clarification upfront from the person so there are no misunderstandings.
