I often hear people saying indifference is the opposite of love. It used to be hatred, but, someone enlightened the whole human race that it's indifference that has to be associated with the opposite of love.
But have you ever wondered when you usually become indifferent to something? Indifference is an evolution. It comes only out of love!
To put it in simple words, love sometimes hurts and it's an involuntary action for us to stay away from anything that hurts. So, in the act of protecting ourselves, we become distant and cold. Most of the time( but not always) it has nothing to do with the opposite of love, if you ask me.
