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

General Introduction to Boundaries from Panahi Counseling:

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

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

I found out I have cancer—I have not told my family. We can’t afford the treatment anyway. Should I just say nothing and let nature take its course?

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

Obsessing about clients outside of work hours.

Serious disappointment when the client cancels a session.

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.

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

Off the top of my ancient head:

What do you think of the Quora group "It's Ok to Be White" for people who are proud of being white?

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

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

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

I've never read the book. What did Dorian Grey do that was so immoral and sinful?

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