If he did not pay the fee, I -130 is not even filed. It is not just incomplete, it is simply not filed.
if he is divorcing you, then he should not even file I-130 for you.
Your chances to adjust status based on marriage are nil.
You should consult an attorney in your area or any immigration attorney on phone to get the advise.
When the I-130 was mailed to INS, did you or him receive a receipt. Often times, people in divorce proceedings will claim the application was never completed etc.... You can contact USCIS to determine if a petition has even been filed for you. Also, an approved I-130 does nor automatically give you teh right to adjust. It only confirms the relationship exists. If you are devorced, the I-130 petition of your "ex" husband would not be the correct current status. You should contact an immigration attorney who can assist you as to what options if any you have. Good luck.
