There is no "idea" like platon theory that would explain love. Love is something complicated easy. Love isnt only smiling, kisses, hugs or stuff like that. Of course, they are very important and they are used to show love, but love cna be explained in a million ways and when it comes to advice from people, it would nevre work becaues evrybody sees love in a different way. For some people can be money, sex, someone loving you back, being with someone special. of course there is where ethics come in play, but love is a wonderful feeling and when it comes from a very special person its even more beautiful and I wouldnt trade being with the woman Im now for anything in the world.
