I've actually discovered in my own 17 years of experience, that almost everyone who is looking for a relationship wants what you would have in a good friendship. From what I can tell, people tend to push it into a relationship if there is sexual attraction, though this is not always the case. As there are many Aspies and NTs or Asexuals that might also desire a relationship purely for the friendship, plus that little extra bit that's love.
Then you get into an entirely new bowl of wax with love. What is love, really? Some people think love is when a person is always thinking about you, and caring about your welfare, willing to do anything for that person. Others think it's more about how honorably someone treats you. Then you've got the people that think it's when someone will always be happy you're around.
It's just a little complicated at this point, heh.
