Therapists ask for phone numbers information. this is for in case they have to cancel an appointment or if something comes up that they are concerned about they can get ahold of the client. it is also for emergencys.

Most if not all therapists unless you specifically state that you do NOT want them to call you, will call to discuss issues over the phone, and will leave messages about things that they are concerned about. for example a clients safety and how they are doing after a hard or stressful session and or situation.

if you and your therapist have not discussed recieving phone calls she is free to do so.

Therapists are not mind readers they cannot snap their fingers and just know which clients are ok with getting phone calls and which ones are not. It is up to the clients to let the therapist know what they the client wants and what is ok.

My suggestion -

tell the therapist you no longer want her to call you to leave ANY issue related messages.

be clear that you are Letting her know that she can call and say she would like you to call her back and then you will do so.

Put it in writing and have that therapist sign the paper if it will help you to explain to her what you expect from her, what you want her to do and what you don't want her to do.
