There is only one marriage in a person's life, and parents watch their children get married only once. No matter how bad their biological father is, he gave you life after all. I think you'd better tell your husband the truth first, so as not to make trouble with your biological father in the future and make your husband think that you have cheated him, and your husband's family may regard you with special respect. You can discuss it with your mother and let your biological father and stepfather take the stage. This is to thank your biological father for raising you and your stepfather for giving you the opportunity.
