But saying that, I can also understand why many people in therapy want to clearly know up front what a therapists boundaries are, especially people who have trauma histories and it is also understandable that you'd want them to stay consistent. If you've been traumatized, how would you ever find "surprises" comforting or safe? If you're someone who has had your boundaries trampled on or if you were never allowed to establish even the most basic boundaries around yourself, then you're going to be someone who is always looking to an outside person to know what is "okay" or acceptable in your interactions with the other person. I think learning to deal with flexing boundaries in the outside world comes at the end of a good, solid, consistent and nurturing therapy relationship.
