<human>: Hey all. My mom is currently planning on divorcing from my dad, who can only be described as a narcissist. I don't live with them as I am in college, but my 3 younger sisters live with the two of them. Basically, my mom wants to divorce him, but isn't sure how he'll react when she announces the divorce to him. He's been prone to just leaving when he isn't happy with a situation, and I'm scared he will do something violent or drastic when she announces it, let alone leave the house. Is there anyway she can start the divorce process whilst making sure he doesn't take their money, wreck the house, or hurt anyone?
