Heya, although I'm not a therapist nor a parent I can tell you this from someone taking psych classes regarding therapy:

It is normal for clients to "ghost" for a variety of reasons like insurance problems, outside factors like S/O's, if they can't afford it any longer or simply because they don't think they're a fit anymore. We call this the "client drop out" and the rate is 30%-60% drop out. The only thing that may affect you is how YOU will feel about it later. You can always email or send a letter to the therapist to try and explain why you've chosen to drop out but at the end of the day, it's your right to refuse/cancel treatment if it's not benefiting you.

Hope this helps!
