Ishaan has done exactly same like post title . He set his love free to choose her happiness and stay happy in life. This is what mature people acts in such situation. It gives strength to other person to move on in life without having guilt in heart . Kisi ko rote rote jaane dene se acha hai usko apni khushi choose karne ka pura haqq hai iss ehsaas ke sath uss insaan ko free karo jisko tumne bepanaah pyar kiya hai.Ishaan is doing exactly same.
