Some love is love without reciprocity... but I feel that love is much more rich when life is shared. Also, constant love is difficult for humans to maintain.

The interesting thing to me about Shakespeare's Romeo and Juliet, is that she demanded constant love from him rather than inconstant love. It's a small passage, often overlooked... but from that one tiny interchange is a clue that their love was not actually infatuation even though it really looked like it. I mean, Romeo's previous history of love was to be infatuated with a new girl every hour almost... lol. But maybe they didn't insist on constant love?

Human love feels inconstant but is really always there, just not always expressed. Divine love is constant but much more impersonal. It would be interesting to experience both with the same person.
