Is love one of life's necessities?

Human beings crave another human's attention & nurturing. Is it just an after effect of being pushed forth by our mothers? Even the most independent souls need love. Life ceases to exist without love. To give love may fill some, but not the entire void we carry with us until our demise. No matter the individual, we all strive to be loved, to be the object that consumes another human being's attention. But, then we become arrogant, we play around with that person's emotions, seeing how horribly warped we can make them. Jealousy, envy. We fill them with false hopes, only leave them on the floor, weeping with the throws of rejection. But, when we receive that one love, it swells inside us. It makes us 'weak at the knees'. Just to see that person is counted as a day complete. It recolors our world as we once saw it, then dull and dreary. It begins to flood our senses.
