My boundaries are firmer than my therapist's. Her big one appears to be that out of session contact must be by phone, at a reasonable hour. And no social media contact. Both of these are just fine with me. Other than that, she offers stuff like touch, and I decline. So I guess I like hard boundaries.

I'm not sure paying for a missed session without notice is a boundary - my dentist would do the same thing if I missed an appointment without notice.
