Think of hearts as life. Not the beating, gross looking thing in your chest, but the shape. Just try and keep up with me here.
So, hearts are life. Now, picture yourself drawing one. Most people do hearts in two parts, starting with the top depression. This is the begining of your life. You climb a small way, being innocent and ignorant to the true ways of life. Then, you start falling as soon as you find out that life is not easy and never will be. You fall, and fall, and falluntil you finally find the one person who you know you will love forever. You meet this person when you are at the lowest part of your life [the bottom point]. This person will lift you all the way back up, up, up to the top of the heart again. Then, the rest of your life begins and you keep thinking, always, about that one person, who you left and let slip away. You fall, yet again, slower, painfully slow, but not as far as the last time. You come back to the place where you began, and you ask yourself, "Why did I ever, let you go?" Then you die, and the last thing you think of, is that person. You want to lift your life back up, but you've finally run out of time...
