What am I entitled to after 19 years of marriage?

I have been with my husband for 22 years, married 19. We are going to be divorcing and I need to know what I am entitled to? He is looking into refinancing the house with just his name, as I cannot afford the house. Am I entitled to anything to help me get back on my feet? I am currently not living in the house, but still paying him the exact amount that I was when I was in the house. I am honestly broke and don't know how I am going to manage. We have two kids in college (ages 21 & 19) that live in the house during the summer and breaks. The older one would like to move in with me when I find my own place. I don't know exactly what I should be doing, I cannot exactly afford a lawyer right now with still giving him money. Any advice?
