My husband controls all the money. How can I afford a divorce lawyer?

Additional Information: We have been married for 32 years. I stayed home to raise our two children. When they were older I starting working until I got laid off fairly recently. Last year I developed many health issues that caused me to not be able to work. I work part time now despite health issues. My husband controls all the money and gives me less and less to pay the bills. I do not make a lot of money. Who moves out since I can’t afford a hotel or apartment? Do I have to work full time despite health concerns or would I be entitled to alimony?
