I think it depends on how you define love.
But I'm on your side. The most amazing experience I've ever had was falling madly in love with someone as our eyes met at a party. I cannot begin to explain the profoundness of my experience. A moment that last for eternity is closest that I can come to putting it into words.
I got to know her better after that, but for various reasons, we were never romantically together.
But I take other peoples point about truly knowing the details of a personality, good and bad, and the deepening of love over time.
As i said, it's all how you choose to define love.
