I'm not sure I'm following you here.

The therapist has every right to want to uphold his boundaries. And I think Lost did know she was breaking a rule by texting him so much, but in her panic she believed that getting the reassurance would be worth the consequence. Therapist has every right to hold her to the consequence, whatever it is going to be. Just because he understands where she's coming from doesn't mean he has to give in. The therapist knows the desire for reassurance is coming from an unhealthy place--one that is always hungry. Constantly feeding it is not the answer.

I'm not sure what the therapist could have done to make this better for Lost. It's obvious he tripped a land mind, but I sounds like he's doing the best he can.
