"Love is a muscle" my dad was fond of saying. You exercise it, and your ability to love grows- love yourself, the people and places around you. Open yourself to love and it will find you as Mc Kenna stated.
I and many people on this board are living a happy life with an Argentine partner, but I think it's not so much about the place, but your willingness to open yourself to the experience and take the risk. The cultural differences *will* drive you crazy, but will also be the amazing spice of life.
