If you have lived in Florida for more than 6 months, you could file for divorce in Florida. However, you could also file in Illinois so long as your husband is there. So you would want to consider what makes the most sense on a practical level, as well as strategically. Consider where witnesses in your favor are in the event you need to go to Court and have them testify. Consider whether infidelity is more relevant to an alimony/equitable distribution award in one state versus the other.
You will likely need to file in Illinois. Illinois is the state where the marriage occurred, where the marital home presently exists, and where the couple last remained as a couple. Illinois law will govern the divorce.
