according to dictionary.com:
1. a profoundly tender, passionate affection for another person.
2. a feeling of warm personal attachment or deep affection, as for a parent, child, or friend.
3. sexual passion or desire.
according to me:
Love is like a circle. If you have one person who cares and gives their energy to another person, solely to make them happy without caring for yourself, and that person gives of themself to you in the same manner, then that's a completed love. The energy flows in a circular fashion and so two people, become each other's strengths, and are unified. This not even considering the physical part of the relationship.
p.s. yes I'm in love.
x2.: yeah... it hurts... >_>;; my circle's not quite complete.
