You should check with your local Family Law court, but you should be able to still get divorced - it will just take a bit longer and cost a little more.
You will most likely have to petition the court to allow you to do it by publication, which means that the Summons for Dissolution must be published in a local newspaper for a specific period of time. This will establish service, which means that the court would then allow you to proceed to file Proof of Service and continue the process to complete the action.
You can do the entire process yourself, but I suggest you obtain legal advice to make sure you are doing everything correctly and using the proper format.
Good luck.
