Empathy for others is going away by time. I have friends that asked me for my opinion on what to do on her dates. It impressed me the lack on empathy she had for the other person, if she did not liked the person she simply ignored the calls, and text (Ghosting). I told here many times to call them back and talk about the reasons why she is not want to see them again. It seems that if you don't like someone now in date is just simply ignore the person and they will go away. The effects of doing what my friend did are very demoralizing for the other person, making the other person open to make the same mistake without a feed back.
