Your T has to create a safe environment for you to say/do whatever you need to progress over reacting would not help you feel that way. She did say it saddened her and that's enough.

One of my ex T's when I told him I was getting married (after 2 wks or less of knowing the guy.) told me, The therapist in me says "That's really nice, what's he like?" but I'm no longer your therapist so. "What are you ****ing crazy? You don't know this guy. You just met him...." So yes T's emotions are muted in therapy but that doesn't mean they aren't there.
