Yeah, me too. Life is totally in danger. It just a matter of when it will happen.
I was in a similar situation, and I did not realize the severity of my predicament. I sought counseling, and did what my therapist and attorney told me to do. ESCAPE, but disappear when my ex leaast suspected. Otherwise, the act of leaving will escalate the violence. Better for you to be GONE GONE GONE GONE.
You really dont have time, you need to get out.. But I do understand if you need to plan. Planning is always good. Do all the things to make your partner think that all is well. By now you know the cycle, and when you are ready to do it right, disappear. Leave..
