Hi Brianswife and welcome to healingwell. Welcome to you as well ejrjwk.
First of all if you feel you are in physical danger, and Brianswife I feel that you are, get out NOW! Your husband is unstable and out of control. DO NOT stay because he tells you he may hurt himself if you leave. That is classic alcoholic behavior. I was battered both physically and emotionally for 13 years before I found the nerve to run away. It wasn't until I finally saw the emotional impact our relationship was having on our children that I made a run for it. If you feel that he may truly hurt himself, then call his pdoc, minister, perhaps one of his family members, or even an ambulance to intervene but don't stay for that reason. If your husband is bp1 and having a psychotic episode he could truly harm you and feel much remorse later but that would not undo whats been done.
And ejrjwk, I'm glad you're sticking to your resolve and not running back this time. Your first priority must be yourself and your unborn child. Perhaps this will be the wakeup call he needs to finally get some help.
Take care and God Bless to you both
You'll be in my prayers
