What is love?

I had this come up recently. What is "love?"I have a theory.https://www.youtube.com/watch?v=-ELFOyzvgPgWell, basically, it's the notion that you're putting someone's needs / feelings / whatevers before your own. No, to disabuse you of the idea of martyrdom, no being a martyr is putting yourself at a disadvantage to, ironically, help yourself.No. This is different.Love is something more than that. Friendship has some more of the "I'll help you if you help me" aspects. Love doesn't have that same expectation -- though it very well has the hope.Or, well, it might just be bunnies.
