Love and selfishness

I can ask a simple question from all of you that why there are only few known love stories in the world of billion of people? At a single look answer looks very difficult to this question. However the answer is very simple that all the love stories which are known today were without any selfish motives. Those lovers never allowed their selfish motives to come between their loves. Today we all put our selfish motives in front of our love. It is very hard to find a love with out selfishness in this world. Most of us only use love for fulfilling their own selfish motives.
