Love is nothing but happiness. If happiness go away then it will be painful. Pain is also one kind of happiness because it remain us about our love.the people who are fail in love are great because lifelong they will have that pain in their heart and they remember their love forever
Everything has two sides the positives and negatives..Similarly when love bring happiness and joy in our lives we remain happy while at the same time when it gives pain we become sad by heart. But a true lover remains prepared for it...
