I am a married guy, my wife is from the same city as I am, but if she would be from another city or country I would still love her. Location is not important, what you have in your heart matters.

I also don't think it matters. However, based from my observations and experiences with other couples, I have seen that most coupes who came from the same area (rural and rural/ urban and urban), are more comfortable and understanding with each other. Furthermore, I also believe that the knowledge of couples towards their cultures and traditions make their relationships more smooth sailing than others who came from different walks of life.

I think it can be an important thing, but maybe not.  It depends on the person.  Perhaps the OP simply met the wrong person.
