What are some signs that a therapist may have poor boundaries with their clients?

Struggling with fantasies of deeper connections with clients, whether sexual or parental or other intense or intimate relationships beyond psychotherapy.

Eager anticipation (or anxious anticipation) of the next session in ways that distract.

Obsessing about clients outside of work hours.

What happens when your partner doesn't see the value in you and continuously hurts you by searching for something in others knowing it hurts you?

Session-expressed curiosities about client details not relevant to the therapy.

Frequent phoning or texting of clients to “check up on them and make sure they’re OK.”

Serious disappointment when the client cancels a session.

Why are people saying that Trump is fat when he is an athletic 6 foot 3 and 215 pounds?

Failing to mention the client in supervision/consultation, out of fear the supervisor/consultant will advise return to ordinary healthy boundaries.

Routinely going over the time limit with certain patients, compromising the time for the next client.

Why did Democrats echo that Joe Biden was greater than FDR and should be put on Mt Rushmore? Why did Democrats vote for Biden blindly in the primaries and deny he was mentally impaired? Was it the lying media, or are Democrats ignorant and gullible?

Off the top of my ancient head:

Sense of competition with persons who are important in the client’s life.

Disclosing feelings, fantasies, and experiences to the client in ways not related to the work the client is engaged in.

I'm looking for an answer from people who consider themselves "Gender Critical", or transphobic, or TERFs, and my question is this - Why would you refuse to use the pronouns someone wants? What does it cost you? Where's the harm?

These items can happen fleetingly, briefly, in any therapy, but if they’re frequent, it’s definitely time for the therapist to get some good, solid supervision/consultation.
