Wow. I would think that moving is the best and possibly the only option. I hope your husband isn't still going to get visits with your daughters. A lot of sociopaths have high IQ's & describes your husband. He is successful on the outside, smart, witty ect... He probably has his side of the family fooled. But the bottom line is he's very dangerous. Out of all the threads that I've come across, this situation scares me the most. The gun idea was good if you take classes to learn how to shoot/store the gun. Maybe get a big attack dog (some can be good with kids) or home alarm system to protect yourself?
