I can provide some insight into how therapists typically approach such situations.
In the therapeutic profession, it is essential for therapists to maintain a professional and ethical stance when clients decide to leave their practice, even if the decision is based on finding someone they feel is a "better fit." While therapists may have invested time and effort in building a therapeutic relationship with their clients, they understand that the client's well-being and finding the right therapeutic fit are paramount.
Therapists are trained to understand that clients' needs and preferences can change, and that's entirely normal. The therapeutic relationship is a unique and personal one, and not every client will feel equally comfortable or connected with every therapist. It's essential for clients to find a therapist with whom they can establish a strong therapeutic alliance and feel safe and supported.
Therapists are encouraged to be open and non-defensive when clients express their decision to explore other therapeutic options. They might discuss the reasons behind the client's choice and, if appropriate, explore any unresolved issues in the therapeutic relationship. However, a therapist's primary concern should be the client's well-being and providing support during the transition.
Ultimately, therapists understand that their clients' growth and progress are the ultimate goals of therapy, regardless of whether they continue working together or seek another professional. Therapists should respect the client's autonomy and their right to choose the best therapeutic fit for themselves.
So, to answer your question, the desirable and honest response from a therapist would indeed be that they do not take it personally or feel bothered when a client decides to leave their practice for another therapist they perceive as a better fit. It's an essential part of the therapeutic process and growth for both the client and the therapist.
