KLS -
I'm really sorry you are in so much pain right now. I know it will be hard to do, but if you really want to get away from him, then the best thing is to go ahead with it. The more you linger the worst things will get emotionally.
The big thing he say's is jws don't kill people and they are the only religon that goes by the bible and understand it.
This is the type of elitism exuded by the JWs that irks me. They think they are the only people with any morals or enough sense to read the bible. Like others have said, there are lots of people that don't kill people. Do the JWs honestly believe they are the only group that doesn't condone killing? I was really having doubts that leaving was the right thing, but reading this reaffirmed my beliefs.
I think it's time you gave your husband a wake up call.
