If your husband files a petition to sponsor you for a green card, it will take 3-4 years for a visa to be available for you. You can check the availability of immigrant visas by reviewing the Visa Bulletin issued by the Department of State each month. Here is a link to the Visa Bulletin: http://travel.state.gov/visa/bulletin/bulletin_1360.html
Although you are still legally married, you will also have to convince the consular officer during your interview that your marriage is still viable.
