Chopin, I was thinking about your experience, and several other people's experiences with their T's changing boundaries. I know that others may disagree, but I do not think changing boundaries as therapy progresses is per se a bad thing. The problem is when your T does it abruptly, angrily or without explanation.

I have rehabbed a number of abused animals. There are things that I will tolerate from an abused animal in the beginning, that I will not tolerate later in training. There is a trainer I really admire, and this is a quote from him: "On a green horse, one that's kind of troubled, I might let them cuddle up to me because it's not a disrespect, they're looking for some support and comfort. But then gradually I know part of the process is that I put him back on the end of the led rope and say, see if you can stay out there and still feel my comfort from out there. But I won't ask him to stay for long. I work my way toward everything I get in small increments, a little bit at a time."

So, your T has let you cuddle, figuratively and literally. Your therapy has progressed and she's trying to get you further away on the lead rope. She's doing it too quickly and with too much emotion. Maybe framing the discussion this way with her next time might be productive for you both?
