First, let me say that I hope you are recovering well from your surgeries and that you have no more need for them in the near future.
Now, yes, you have options. You can ask the court for post separation support, alimony, equitable distribution (dividing property), and your attorney fees. The court can make him keep medical insurance on you, which you obviously need.
As far as the threats of physical harm, etc. I would suggest a domestic violence restraining order.
I am sorry that you feel like you are alone in the valley right now, but keep your eyes on the sky and your hopes up. Take action and see an attorney, even if you have to borrow the money now. A judge will definitely not like his behavior. Best of luck and keep us posted!
