It is hopefully not that impossible that you think. You have several options. Talk to a divorce attorney in you area. Need to know more facts in order to answer your concern.
If you truly don't know where he is and you have no property that the judge needs to take from him, a divorce is actually pretty easy. Your attorney will need to get permission to serve him via publication. That means it is published in a paper for three weeks that you are seeking a divorce. Then, the court can sign off on the paperwork. It costs extra for the publication, but it's not difficult. Get an attorney and get it over with.
You need to speak with a lawyer, and/or get your complaint for divorce filed. You can attempt to have him served at his last known address. If he is not found, or is avoiding service, he can he can be served by publication.
It is not necessarily harder to get a divorce in your situation than it is in a situation where the divorce is contested for any other reason. It is however almost impossible to handle such a case yourself and you will need to hire an attorney that is familiar with the process of either effectively using a private investigator to locate your spouse or following the proper procedure to have him served by publication. I will warn you that service by publication can be expensive as can the services of an investigator. I would suggest using Facebook and contacts with relatives as a means of finding him yourself. You can save yourself a lot of money with an uncontested divorce and it is well worth your efforts.
Actually, getting a divorce in your case would not be difficult. If you do not know his whereabouts, you would file for a divorce in the usual method but then ask the Court if you can serve him via publication. You would definitely want to seek the counsel of a licensed attorney and someone who is very familiar with the procedures as it is largely a procedural matter. You should contact an attorney as soon as you are able to at least arrange a consultation. I would be happy to discuss any issues with you further as would any other attorney who practices divorce law. Keep in mind that most attorneys do not charge a fee for the initial consultation. Good luck.
