You most certainly are not stuck Scaredwife and it is possible for you to move forward with your plans, move, collect yourself and begin your own recovery. I wonder why you would consider staying at this point. Your husband needs to know, that you are serious and are no longer willing to live with his abuse. He needs to see the reality of the situation, since you have a plan in place why not move forward with it
I also hope that you plan to go forward with you visit home, by yourself, and spend time with the people who love you and who will support you. Going away may very well help you get some perspective.
You need to protect yourself, not him.
Why has the cancellation of the intervention changed your mind???
