I agree with this on some levels. I've never been in group therapy, so I can't judge RTS' H's situation. Perhaps it's normal, maybe it's not. I just know what my opinion is.

I agree for one-on-one therapy that it is a safe place to say anything one wants to say; but for the client, not the therapist. That is why I had a problem with T complaining about her H (about something moderately serious). It's my therapy, not hers. She crosses that line on occasion. Normally, I like hearing what my T has to say on many matters and when she talks about herself, I feel safer about talking about myself. That being said, there should be a boundary there.

However, I know how my marriage works. We are a united front. We each strive to only speak good of one another when we are apart. We defend the other's actions, right or wrong, when speaking to people who ask questions. We have each other's back. If we happen to disagree about something, we take it up with each other, not people outside of marriage (therapy excluded).
