You need to seek the advice of an immigration attorney.
This is extremely problematic now that you have attended the interview and represented that you were still living in marital union. You can try withdrawing, but speak to a lawyer.
If they deny, you may not be in a position to refile - they may take the position that you misrepresented and so take action to take away the green card/remove you.
Speak with an attorney before doing anything further.
You should consult with an immigration attorney immediately.

J Charles Ferrari Eng & Nishimura 213.622.2255 The statement above is general in nature and does not constitute legal advice, as not all the facts are known. You should retain an attorney to review all the facts specific to your case in order to receive advise specific to your case. The statement above does not create an attorney/client relationship. Answers on Avvo can only be general ones, as specific answers would require knowledge of all the facts. As such, they may or may not apply to the question.
Agree with my colleagues.
