No matter how hard you try or love, if others don’t love you, you shouldn’t try hard to keep them with you. Let them go where they like to live. I know many people who know tricks. They plan, say sweet words, do some acting and succeed to make fool others and make them do whatever they want to do. In most cases they do this for money. They don’t care that because of their attitude a wife is missing her husband or a child isn’t getting his father’s love, they only care for their own benefit.
If you don’t know tricks or don’t want to play with your beloved one, let them go. If they really love you, they will come back to you by themselves. If not then live your own life that love wasn’t for you, somewhere else your real love is waiting.
