So the petition has probably been abandoned. This won't really affect YOUR filings but one thing I advise ANYONE in this situation is to think very, very carefully about sponsoring a new spouse. Don't rush to get married - and certainly don't rush in order to legitimize someone's presence in this country.
Sponsoring someone is a very big commitment - it can affect you for the rest of your life even if you get divorced. You may be liable to support your spouse, should you get divorced, financially for a long, long time.
With that said - has he actually filed for divorce yet?
