Why does love hurt

Love burns as follows; You leave or he leaves you, and it will deceive you, and this is so bored, you can't stand it anymore. There is patience to some extent, and then you can't hold yourself, you cry. But after a while you forget.

Life continues, the pain of your girlfriend or boyfriend is behind. But when someone who thinks and gives importance to you is no longer remembered as the pain of love that has remained in the past.
