I recently divorced from my husband. And to save my children AND myself further mental abuse, I agreed to everything he wanted. He is a narcissist and only responds to getting what he wants. He continually harasses me and has made my kids not want to be around him. I just wanted to be divorced from him. To be rid of him. But he uses the divorce agreement to get what he wants. And since I just gave in to him, I don't think there's anything I can do. When can I take him back to court and fight for me and my children?
