How can you "recreate" marriage in a state where marriage is not legal for you?

My partner and I (both females) are interested in getting married but it is not legal in our state (Georgia.) Aside from having a wedding, how can we recreate the legal benefits of marriage without actually being married? I’m looking for specific information on which forms we could fill out, and where to get them, in order to create typical “married” rights and privileges. Hospital visitation, home/property ownership, etc. I’d also be interested in a good summary of the legal benefits of heterosexual marriage as I’m not even sure what all that entails.

Thanks!
