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

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

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

Off the top of my ancient head:

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

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

Serious disappointment when the client cancels a session.
