My husband left me for my sister

Hello, My husband of 14 years decided he was in love with my sister and now we are divorcing. As I made 1/5th of what he made it has left me with a lot of debt and little income. I am currently staying with family as I can not afford my own place with everything I currently owe. I would like to be able to have a place of my own for me and my children instead of having to rely on family. Please help
