I would not do well with a T who had hard boundaries. I need a T who feels warm, caring, and affectionate. I don't need between session contact (though my T does allow it and I have used it occasionally), but I do need human warmth during the sessions. That said, I think consistent boundaries are even more important than whether they are loose or firm. I need to be able to know what my T's boundaries are and I need to know that she will not unilaterally change them. My T never initiated a conversation about boundaries or volunteered what they were but, over time, I asked about them and she has always kept them the same. They are different for different clients but once she offers something, she doesn't take it away. (I mean, if a client violated her boundaries, she might make them former but that isn't an issue in my case). knowing what T's boundaries are and that they won't change makes me feel safe and allows me to trust her.
