Why do we feel sad when we lose the one we love?

Piano

Just because not willing to give up this love, memory. and firmly believe it is true love, it is a treasure in your life. (只因不舍，不愿放弃这份爱，不愿忘却这段记忆。而且坚信这就是真爱，生命中的瑰宝）

Because you have ever gave him or her your love...As a result ,he or she is not only a person in your life,but also a part of you.

Maybe because we still love the other one. Love is magical. Think about that: two people, maybe they are completely strangers before they fall in love. But once they fall in love, they are so close to each other. They can almost do everything for the other one. But once they break up, they are strangers again.

Because we had been so infatuated with each other and we shared lots of sweet memories.But heartbreakingly,we couldn't be with each other any more. The separation is the last thing for anyone who's immersed in the love moisture to imagine.So if you don't have any feeling,it just proves you didn't actually fall in love and gave your heart to him or her.
