Hello, to asnwer your question, you do not need to file in the state where you were married. You may file wherever you actually have residence. So if you live in GA and you meet that state's residency requirements, you may file for your divorce there. Your spouse may then consent to the jurisdiction of the GA courts by appearing in the action once you've filed it.
In Georgia, you file for divorce in the county in which your spouse resides. If your spouse is agreeable, you can file for divorce in the county where you reside, if different from your spouses. But no, you don't file where you got married.
