No, your boyfriend (soon to be husband) is not responsible for your loan predating your marriage. That means that they cannot put a lien on his home, ownership of which also predates your marriage and which is separate (not marital) property, *unless* he puts you on the deed or title; if the does that, you become part owner of the home, the home becomes your asset as well as his, and the creditor can then reach the home and put a lien on it. So do not go on the title of his home.
