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

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

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

Off the top of my ancient head:

How can you maintain self-control?

General Introduction to Boundaries from Panahi Counseling:

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

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.

Should Pete Rose's record as the all-time hits leader be recognized and celebrated?

Serious disappointment when the client cancels a session.

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

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

How do I know if he loves me? When he wants me to be his gf he make time for me and send me morning and night messages and done everything to melt my heart. Now I am his gf and he don't treat me that way now.

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

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

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

Why do I feel worthless most of the time?

Obsessing about clients outside of work hours.
