What can be done if we got a divorce and bank released me from all obligations on the loan but both names on the deed?

Me and my husband got a divorce and my husband refinanced the home in his name only the bank sent me a letter releasing me from all loan obligations. His attorney wanted me to sign a quick claim deed and somehow it never went through my ex husband died and the mortgage company wants me to sign over the deed to the house and I refused to do so. They are now tiring to sue me for the money left on the mortgage of the home. Am I still obligated for the balance of the mortgage also the bank is foreclosing on the house and states I am responsible for the loan even after I received a letter releasing me from the mortgage obligations because I refuse to sign the deed over to them. I live in the state of Indiana and can’t afford an attorney at this time due to my business closing down. I am out of a job my kids still live in the house can the bank make me responsible for the remaining balance of the mortgage what rights? Do I have when my name is still on the deed am I responsible for the loan or what can I do?
