I let the love for family and friends be for what it is in the discussion here.
But there is this chemical substance that we make in our body... It's called
phenethylamine. Before the age of...10 (as I recall

) this does not exist in your body (or your body doesn't react to it; either way).
But when it does, you fall in love. The question to whom is worth discussing. I used to fall in love with girls who were blond, pretty and cheerful. Now I have a girlfriend (still first one ever) who is not blond, though pretty, and also cheerful, but she's different than all the other girls. (So apparently, there's a difference between puppy love and 'true love'.)
I do believe love is an emotion. I haven't reached the point that this kind of love is obviously abundant in my life, like when you're married. She's my girlfriend for a half year now, but she's in Norway now

and we miss each other so much, that we'll love each other as much as we always have until she's back for some time. (That does make it kind of romantic, doesn't it?)
By the way, my girlfriend thought she was happy with her live and not in need of a boyfriend, but then she met me. :love2: Now I'm most important in her life and she is in mine.
But to come back to phenethylamine: it's like a lot of other organic molecules an
emotion trigger. So the fact that love is an emotion is scientificly determined.
