It is human condition to want affection from other beings. It is better to have loved and lost than to have never loved at all. Love absolutely hurts people who are blinded in what they conceive as true love. I don't believe that the pain is a coincidence. Love is the source of the pain. We feel the pain because we are brought up on myths and mysteries of "true" love. However, humans learn best through experience, and what they conceive as true love isn't always it. They are tricked. That explains all the divorce in the United States anyway. But because we are able to learn from our mistakes, it makes the conception of what we think is love significant. It makes people stronger. Time heals all wounds, and once they are healed people can take the knowledge of what they've learned through this significant experience in order to continue their search for their soul mate. Sort of like a trial and error test. So, we feel pain in order to gain the most from the experience because heartbreak can be significant to changing a person's life and allow them to continue spreading the love.
