I left my first T in the middle of really nasty conflicts that had nothing to do with what I was in therapy for. Twice, because he convinced me after a~year break to go back to "resolve" things. Never worked and actually made it much worse, so I quit again and this time for good. I am not sure there are always "things to solve" when a therapy does not work or when client and therapist have conflicts. In my case, for example, nothing could have resolved that I really disliked almost everything about that T, had zero respect left for him, and found his approach useless for me. It wasn't transference for the most part but a massive personality clash. My leaving and not beating each-other further was better for both of us, I think.
