Love at first sight or does it develop over time?

Love at first sight is possible. It coincides with the spiritual connection with an individual. Empaths are more likely to discover this anomaly.

I don't really believe in "love at first site". Interest and infatuation? Yes, but not real love. Love is being in at least a year+ relationship living with your significant other and knowing each others strengths and flaws and still knowing they're the person for you. That's not to say infatuation can't grow into that. It certainly can, but to say "real love" has blossomed in less than a month of dating someone is about as believable as some HS freshmen thinking they're going to be with their current bf/gf the rest of their lives. Statistically, they'll be lucky if they relationship lasts to their junior year.
