There’s a pretty obvious mis-use of the term “red flag” in this post. “There just isn’t chemistry” might be a valid reason to move to a different therapist, but it’s not a “red flag” even if that remains true after a year with them. A red flag isn’t an incompatibility in a relationship, it’s a warning sign of danger, or at the very least of something that should be considered an objective failure that makes them worth not just avoiding yourself, but recommending others do the same.
