Love, is a verb, a choice to do what is best for someone, and put them first, even at a cost to yourself. Love is not an emotion, it is an act of the will. Being "in love" is the set of emotions that come with that choice to love someone.
Being in love is a fairy tale that people use to describe love with sexual over/undertones. Love is just love, the relationship is what dictates how you love. But it is all conditional and a personal choice,more often reciprocated than born anew.
