It’s a trap! If you Google “couples therapy with a narcissist”, it will explain that it is a waste of time. Therapy only works when the participants are honest and willing to work on themselves, which a narc is not capable of. I would get therapy for you and your children. I have court ordered family therapy. It makes me sick to think they are ok with exposing me to my abuser, but I am just grateful for an extra pair of eyes on the situation now.
