I often f'up in CBT therapy, like not fully doing the homework. CBT T will discuss the roadblocks and then assign a more attainable task. I don't hear him give me any hint that he would dump me over it. I think I'd have to be non-communicative and noncompliant for him to refer me.

I can see a bad T pushing too far too fast, but I see that as a therapist problem, not the modality. There are poor T's of many stripes.
