Well the man who is the father may not have a choice unless you want your husband to retain paternity, and he should have thought of his wife and business prior to making a child with you. I don't think you can disestablish paternity without naming someone else. Your husband may be able to disestablish paternity as part of the divorce, but I don't know that you can initiate that without naming someone else.
Perhaps remind your husband that if he maintains paternity of this second child, that the second child will also be part of child support calculations.
