You can get a divorce with out there knowledge . You must put an ad in the paper and made ALOT of effort to find them .. I've done it in Alabama. My wife was on ICE IN LA... Did you get any papers? Do you love in the states? sorry for your problems that your going through... it's the saddest I've ever been... hang in there
You might be able to get these details from your local court. If not, contact your attorney and ask them about this; there is no way you could have been divorced without your knowledge and by extension your attorney's.
