I refuse the word "love", because everybody is talking about a different thing when they say it. "Love" is just a word that confused people use to describe their feelings, without knowing what the hell is happening. And that's ok, but I find it mind-boggling that people are often trying to discuss this on a scientific level. Ask any girl if there's a difference between "being in love", "feeling love" and "true love". Or better, don't.
Might as well do away with the word, and use more direct words to describe what you are feeling.
Affection, attraction, sexual attraction, loyalty, partnership, safety, power, etc.
