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

Obsessing about clients outside of work hours.

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

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

What happens if a parent refuses to let their child be transgender? What happens if the parent tries their hardest not to allow their child to be trans, like flushing every bottle of their trans child's HRT down the toilet?

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:

Serious disappointment when the client cancels a session.

So who has worn a cock cage. One of my guy FWBs put one on me last Sunday and left with the keys? I was very nervous at first but have calmed down. Told me he'll unlock it tomorrow.. Let me know.

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.

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

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.

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.

How do I develop the patience to read books?
