Unless you or your husband were previously married (or are incestuously related), I believe that you may still be able to receive a dispensation to regularize your marriage. I would recommend you discuss this with a knowledgeable priest.
Yes, my husband was previously married and had children. But before that we were college sweethearts, and I never married, until he came back to me. He attended church with me on Easter, but he does not accept Jesus.
Thank-you for your concern. Happy Easter!
