Morningdove, first of all, hope you feel my hug and positive vibes.

You immediately need to protect yourself in someway. Can't you escape to a friend's or relatives place. Even that will only help you to get calm and plan for the necessary action-report your husband. By all means he sounds seriously sick and you need to get the police.

Take deep breaths and think how you can get out of this relationship as fast as you can.
