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

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

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

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

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

Obsessing about clients outside of work hours.

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.

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.

Serious disappointment when the client cancels a session.

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