Love is a genuine feeling, articulated through intimacy, sense of empathy, reverence and truthfulness.
It is really not confined to intimate relationships; it can be love for parental, roommates, citizens, perhaps evolution or an archetype.
Love means recognizing someone nobly, being together them in their sadness, and not awaiting everything in refund. It here is not an feelings, but a good mix of pledge, show concern and respect, which worsens over moment.
