I am confused about how many therapists we are talking about here. Your therapist is not your sons' therapist? Or is she?

If they are two separate people, it sounds to me that the problem is your therapist, and your sons are okay with their therapist and the changes there? (Though I find it creepy that she "weans" clients.) If they are one person, can you find a therapist of your own to help you individually? Because help for you translates to help for your sons, even if they see a separate therapist.
