Well I really like this girl, and I REALLY like her, but I don't know love. I don't think she even notices me though...
Remote attraction/lust is considerably love -- we do not have a measurement which displays once something becomes "love," because the term itself is manmade. As stated before, it's a mix between lust, attraction and attachment. Obsession even plays a factor in "love." People assume the lack of definition is due to it being a mystical concept, but it isn't. It's our lack of measuring the specific fluctuations per person. It's all relative, because it's thousands of processes working together to prompt (more initially in our species' development) offspring.
This isn't to say it isn't real or is easy to understand. It isn't a form of magic, though.
