How do you find "secure" attachment with a therapist who will end sessions if you can't pay them? How is that a secure relationship?

Edit: I want to edit to add some things because it seems like alot of people are not understanding the point of my post or the background behind it. In no way did I say that therapists don't deserve payment for their services, this isn't about boundaries, and no place in this post did I talk about unrealistic expectations of client/therapist interactions. Its well discussed in trauma recovery literature that cptsd recovery centers around a few things, one being developing a secure attachment to one's self and another to a safe figure outside of one's self, these are not the only factor of recovery but two big ones. Typically, because cptsd usually means that a person's family, friends, partners are either absent or not safe, that "safe other" person can often be a therapist. Pete Walker, a pretty well known cptsd therapist, talks about this extensively in his books. My entire point of this post, is to debate and challenge the viewpoint that transactional monetized relationships can be "safe" or "secure", that's all I'm saying here. I'm an individual that has gone years without therapists in my life or any exterior support system, and I have strong boundaries within a therapeutic relationship and don't expect anything of a therapist that is not within the bounds of a professional therapeutic context. Any other assumptions of my conduct in therapy are incorrect, I've stated my viewpoints and the specific issue I have with this individual therapist and therapy in general clearly.

My therapist argued with me that every relationship in life is transactional when I said there's definitely no way I'll ever securely attach to a transactional relationship. To me, there's a big difference between emotional reciprocality, and literally a relationship being terminated because you don't have enough money to pay them. I'm going through the lowest times of my life and my therapist is very high end expensive (over 200USD for 50 minutes), not willing to do sliding scale and they have not helped me that much for all that money. And I've brought up my specific needs many times and not really been heard, plus the things that we are doing each session aren't actually working at all for me, and I've brought that up to but they kindof just act like the issue is me, which I have no problem doing the work if it is me, but I'm constantly not being heard that the techniques and suggestions they are making are not helping me, AND paying super high fees out of pocket. I know it's probably time to just terminate this theraputic connection, but this is just one of many therapists I've tried, I feel I'm just paying super high fees to have someone to talk to and not be so isolated it seems. How can anyone securely attach to a therapist when the relationship revolves entirely around money?
