Are bankruptcy laws federal or do they go by state laws?

I have 60 grand in medical bills and was going to file for bankruptcy but heard that that doesn't cover medical bills anymore. I want to get married but with tha much money owed I think they would go after my honey for the money. Would they? These are the questions, are bankruptcy laws state or federal? does bankruptcy cover medical bills? would they go after my honey if I married him for the money I owe
