If your husband is a US Citizen and active duty military, I have several recommendations:
1. Hire an experienced immigration attorney immediately!
2. Do not leave the U.S. until your current immigration status is resolved. If you have overstayed your Visa Waiver status by more than 180 days, you will trigger an unlawful presence bar if you leave prior to resolving your immigration status.
3. As your husband is a member of the military, with your attorney, contact USCIS for possible expediting of your case. There is a special unit within USCIS for servicing cases for persons related to active duty military( http://www.uscis.gov/military).
4. Additionally, under INA § 319(e), you would be eligible to apply for naturalization to US Citizenship upon approval of your lawful permanent residency pursuant to his orders to be stationed overseas.
