If you are all about service, then move on. You can let her know the exact reasons why you have decided to move on especially when the services that were provided are no longer continuing. Maybe she has a significant other who doesn’t mind her being in the business but does not want her to provide a certain service (ie cim).
I had a regular who messaged me telling me she was no longer offering all her previous services for personal reasons. For me, not a problem and I let her know that. She appreciated my understanding and when we met it was normal as before. Maybe testing me? Regardless she was amazing to spend time with and that is why her service limitation warning was not as issue for me. Plus, if I wanted the service I could always go to someone else.
