Allow your T to make those mistakes. My T has made tons of little mistakes like this and I allow myself to be hurt by them (because it hurts). But I also allow myself to be honest about them - the way you are being. If you feel that the air is still not clear on this (which it shows it is still hurting you) than tell her about it.

There are roots to how the response triggered you. And I think it is worth the energy to examine those roots. You can both look into the situation without any malice towards the people involved in the situation. I learned how to do this after a "small" rupture with my T by going into session and saying "I need to talk with you about my T. But today you can't be my T."

You deserve to address this issue. You can benifit from what you learn because of it. Ts will make mistakes. A good T has the ability to use the mistakes as a way to allow the client even deeper insight.
