Doesn't KY allow common-law "marriages"? As it was explained to me, this is when a couple live together and present the image that they are married.
After speaking with a friend who is rather knowledgable of the Constitution and ammendment process, I don't think we have to worry about an ammendment coming anyway, as heated as this arguement is. I believe the last ammendment to the Constituion took around 200 years to pass. MI was the hold out. Don't quote those figures exactly - My memory sucks lately and he's an IU Hoosier.
