It takes courage to tell someone you're not going back, and tell her why. The easiest is to just to walk away. Then she's trying to figure out why you never came back. If you told her it's because you don't have the cash, she's not going to start giving you freebies. But at least, she'll understand and not start self-guessing herself about what may have gone wrong, and if she was that bad or that there's something wrong with her. It's still a professional relationship. But imagine, you're switching lawyers mid-case, or break all contact with your dentist. Some of the latter may not care, or even notice that you're gone. Others might wonder why their client never came back, as though their professional competence was in question. Plus, just because it's a professional relationship doesn't mean there's not some sort of personal bond and loyalty, at least with one person. When you meet your SP, does she seem happy to see you? Are you happy to see her? There's a bond right there.
