Get a lawyer now. In some states I think you could be as responsible as your husband for the mortgage. Don't forget to divorce the creep and take him for all he's worth. Maybe you can even force them to buy you out of this house of theirs or sell it and share any proceeds with you. Community property baby.
Discovering that your husband has been living with another woman and they have bought a house together is a difficult situation. It's important to address the issue with your spouse and have an open, honest conversation about your feelings and concerns. Seeking the support of a therapist or counselor could also be helpful in navigating through this difficult time and deciding on the best course of action for your relationship.
