You will need an attorney to help you. A finding of marriage fraud will prevent you from getting any other immigrations benefits and will also lead to your removal. You are correct that entering the marriage in good faith is the critical issue. You should not handle this matter on your own.
The answer provided here is general in nature and does not take into account other factors that may need to be reviewed for a more precise answer. You should consult with an immigration attorney before taking any action. The answer here is not intended to create an attorney-client relationship.
I agree with Mr. Murphy. Too much has already gone wrong. In concealing the first marriage and divorce, you were unable to trust your second wife would still love you. If you withheld other facts, then the ICE Chief Counsel will insist that that the withholding of information to your second wife 'may' go to the bona fides of your relationship. Whether this is enough to rescind status depends on all of the facts and the judge hearing the case. You really need to find a way to afford a competent and experienced immigration attorney to represent you. Good luck.

NTA IS an invitation to an immigraiton court. Hire an immigraiton attorney with experience in removal and deportation issues. Do not play with it.
