Nothing, because love is not a necessity in life. There are studies that say love doesn't last more than three months, and others that say even the most harmonious couples will want to leave each other many times in their lives. Life is complicated, and even more complicated is the human heart. The human heart can hold all things, and it can also be vindictive.
The human heart can be infinitely large, large enough to embrace the world; the human heart can be infinitely small, small enough to be jealous of sisters and brothers. The feeling of love will not always occupy the majority of a person's heart no matter what. The more life moves forward, the more things need to be done, and having the ability to earn money to support oneself is more important than having love. Love is a perk that comes with having the ability to live independently.
A person without the ability to live independently, unable to take responsibility, even with love is a tragic end. Having love is just a matter of taking things for granted. Sometimes love is the driving force of life, sometimes love is the original sin of life into the abyss, and sometimes just the flavor of life. After life has a greater goal, higher pursuit, will realize that love is not the most important thing in life.
Love is the beauty of the road of life, have it, life will be more wonderful; without it, the road of life can still go on. I think it is the top happy thing for a person to have his favorite career and fight for it. Have love, life will be more a sweet more a good; no love, life can still have another wonderful.
After all, love needs two people telepathically, you love me and I love you, so the love can be called perfect, but the world is full of people, encounter such a person, than to be struck by lightning is still difficult. Shen Congwen said: I have traveled to many places of the road, traveled to many places of the bridge, have seen many times the clouds, drink many kinds of wine, but only loved a person who is the best age.
The average person may have loved only one, and then none, but the story of life goes on. Also there are many people who may not have loved even one and their life is over, but it doesn't stop them from being wonderful in other ways and living a rich and meaningful life, does it?
