I still have to think about what you said, because it’s totally wrong! And there is a big problem with this sentence. It must be a fallacy that your ex-girlfriend summed up after watching too many erotic TV series or movies. After watching a movie, you go home and change your signature to the movie dialogue. The content of a paragraph is the same! What your girlfriend is saying is that those who have profound experience and mature thoughts, as well as those who commit murder and arson and commit heinous crimes against human nature, have all been hurt or are disappointed with certain things!
Fortunately, you two are separated. Maybe one day you will watch a movie about love and death, and your mood will get too deep, and you will go home and set up a fire and light up the sky lanterns for both of you! To prove that this is the eternity of love! This is fun!
