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.

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

Obsessing about clients outside of work hours.

Is it legal to record a conversation with a therapist without their consent or the consent of the other person involved?

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

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

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

If women aren't shallow, why do most tall, good-looking men have girlfriends?

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

General Introduction to Boundaries from Panahi Counseling:

I live in Massachusetts. Are there any resources here for people that are being harassed by voice to skull, etc.?

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.

Serious disappointment when the client cancels a session.

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

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