If you are still maried I would refile your adjustment. Not only will your chances increase (because Im sure you will use an attorney this time) but your EAD will be renewed while during the appeal your EAD does not have to be renewed.
More information is needed. In these situations, if an attorney has not witnessed and prepared the appeal, then it is hard for an attorney to know whether the appeal will be successful. If the appeal is unsuccessful, then this can complicate any effort to pursue matters such as an employment authorization following the appeal.
Marriage fraud is when someone marries for the sole purpose of securing a green card. This may cause permanent damages to an immigration record depending upon how the matter is handled.
There may be options, but recommend an appointment with a candid and experienced immigration attorney to determine how or whether to pursue your case further as a matter of discretion.
The above is general information and does not create an attorney client relationship.
Its not too late, but your case will take lots of work and the intervention of an experienced immigration lawyer. If your I-130 has been denied, you will need to re-file it right away. You will be able to file a new Adjustment of Status only if you have not been placed in removal. Once you are in removal, you will need to adjust before the immigration court.
