Most of you who have been involved with a sociopath have been to therapists either with your partner or individually. Therapy is critical to healing from the PTSD of these relationships from control, abuse, manipulation and deceit, and hopefully you have found a therapist who knows techniques for helping PTSD.
There is also the rebuilding of self and the grief of loss that therapy can help with, not to mention the potential stressful impact of divorce on yourself and any children. It would be fortunate if your therapist understands the type of relationship you’ve been in and the person you were with. This is all necessary and important, but there’s a critical piece missing to healing.
