Our minds so stop hearing things after we hear certain words that shut us down.....I am so glad that she was able to express what you were unable to hear the last time. It's understandable that you weren't able to hear the good part of her being willing to continue on with you but having better boundaries in place.......
Maybe that's good reason when there is good & bad news to express the good news first & then the bad because otherwise, the good can end up being shut out by the time it's expressed.
Sounds like she might be rather NEW to psychotherapy? Or maybe has never worked with someone with the difficulty of problems that you are going through. Sometimes it's so easy to start down a path & without knowing it.....get beyond safe boundaries.....then it becomes necessary to take a step back.....this happens in all kinds of relationships, not just that with one's T.....usually they are more knowledgable about boundaries......that's why I was wondering about her experience level?.....but she does sound conscience & that IS IMPORTANT.
Sounds like you will both be in a better place with each other now that the boundaries have been established & may be able to progress even farther than before
