I think your anger stems from you feeling trapped by her actions.
You need to take action to no longer feeling trapped. If your lawyer says its alright to move out the get going. Make appointments to look at new places. You need to take action for yourself at this point. You have already stated that you will not stay in an open marriage. The only way for you right now is to get going and get out. Why would you stay there in an un healthy situation? Why wouldn't you find a healthy situation for you and your kids?
Right now you are feeling helpless. You need to change this by taking action.
Standing for your marriage does not mean accepting being abused in the fashion you are enduring at this point. You are only a hero for standing and taking this abuse up to a certain point, after that you become a self made martyr. Don't become a martyr.
We are all here in support of you Gordie. Sometimes one of us has to tell another to get going to take care of yourself and get yourself out of your hole you are in.
