It's true your definition of love. But, the love is dangerous because you can feel dependence for that hearth or love (and that love suffer a lot). Sometimes, We confuse the true love with the goods moments. Or, sometimes, people is so bad and they only want to be egoist. The egoism is not true love. I know what I'm speaking you. When you feel true love, you don't want that person suffer and you do something for that don't happened.
