If you do not love her/him , please let go, so other people have the opportunity to love her/him ; if the person you love  gives  you up , please  release yourself, so that you  have the opportunity to love others. Some things you like much  do not belong to you, some things you  nostalgia  much  are  destined to give up, in life there are many kinds of love, but do not let love become an injury.
