I canceled on my T earlier this year, after a difficult session, then a few email exchanges where he just didn't seem to get what was going on with me. He replied with something like, "I think it's probably better to discuss what's bothering you sooner than later, but I respect your decision to cancel." And he said he had multiple openings that day if I opted to change my mind (I canceled a day or two in advance). So it was like he was nudging me a bit to come in, but not pressuring me. I think that was a good balance. Because if he'd just been like "OK, took you off the schedule," I likely would have felt rejected.

(I did end up rescheduling for the day after my missed session, but I consulted with another T in between, which I told him about. We resolved things.)

I think T's are trained to not "chase after" clients. That it's somewhat unethical for them to be like, "No, you need to come in so we can talk!" Partly due to respecting their clients' autonomy, but I think also due to the financial component.
