The part about having therapy without your consent, is you consent necessary? Do you have joint legal custody and/or is it spelled out that decisions on care are to be made jointly? If not then this is another thing that needs to be highlighted.
It is true that I did not have joint legal custody when my son first saw the therapist, but I lived with the son for all 42 of his months at the time (except the 1 month after I left my ex and she went to the T). I also was seeking joint legal custody at the time my ex took him to her. I know the T can legally say I had no rights.
At a minimum I want to write up what my experience was. The T's attacks on me were a reason I lost my good job and have not been able to recover financially due to her attacks. When my son is older, he should know how this therapist exploited him to help in a custody battle. I want to explain to my son somehow someway why I have no place to live now, why I have been between jobs (not able to pay Child support) and my life and $ is not what it once was. I must take responsibility for this, but the T played a big role in my downfall. I don't want to attack my ex in this note, so it can be tailored to what the T did. Maybe even posted on a website but leave my family's name out. And give the T a chance to respond.
For example, if you were having surgery to remove a wart and the surgeon made a mistake and removed a testicle or breast instead, would you not complain about the damage done? You would just say that is in the past and move on with your life? The damage in court was over 2 years ago and I have had trouble moving on while this T continues her reign.
