She does seem to have a casual attitude to continuity. I have never had a T cancel on me. The Ts I have seen have believed that the regularity of the sessions is important and gives a stability to the process. My Ts have always considered that breaks have an impact and they always gave a lot of notice about breaks and discussed them. I felt an impact when I varied the frequency of my appoinments, I trialled going twice a week and couldn't decide if I wanted to do that because of the cost, so I chopped and changed a bit and that created some difficulties. That showed me that I need consistancy and regularity, either sticking to once a week or sticking to twice a week.
