I've never hit any boundary of any therapist I've ever met with but they have sure hit one of mine now and then I think I called one therapist twice in the three years I worked with her. I did email occasionally with her following a difficult session. The reason I emailed was to off-load some of the toxic feelings I had following a difficult sessions; I wasn't looking for a response and I let her know that if she thought a response was needed, that was fine, but it wasn't necessary that we could discuss the email at the next session. Sometimes she responded and other times not. Either way was okay with me.

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.

Personally, I think many therapists enter the field with poor boundaries themselves and they overextend themselves to clients, trying to "love" them into good mental health. Bad bad practice. Why? Because they often get overwhelmed and frustrated when clients actually take them up on their offers of endless hugs, phone calls, emails, texting, reassurances, extra sessions, extended time limits on sessions etc. and then, when they reach the end of their tolerance of said behavior, they end up terminating clients and putting the blame, once again, on the client. I've seen it happen enough times on this forum.
