Justbreathe, I think it was your post. I know I got it from someone's thread on PC.

Please don't be offended by this: even if you invited her, a therapist isn't supposed to have social contact with clients outside of the office. So by her coming, she may have gotten you confused on what the appropriate boundaries were.

Here is what I think is a good example: Lets pretend that I asked my psychiatrist to lunch. The psychiatrist is supposed to know that that type of behavior is unethical and counterproductive to a therapeutic relationship; therefore, he wouldn't allow it.

The boundaries are there to protect the client. That is why therapeutic relationships are only one way. If my psychiatrist became my friend, his needs in the friendship would have to be met too. Then he would lose all objectivity in trying to treat me. This is why the boundaries are so important to follow.
