This is a difficult one. The number one rule of getting along with a narcissist is not to question their thinking or rational. However, when they aren’t showing you any empathy and you are having difficulty in your relationship with them a little empathy from them goes a long way in potentially solving the relational issue. The best way to cushion the criticism is therefore to start with a positive and end with how you feel.
I love how you used to listen to me, it made me feel very understood and special. Recently I have been feeling sad and rejected because I sense a difference in how you listen to me. Please may you try to listen to me the way you did back then now?

Having said this, a true narcissist will have great difficulty cultivating empathy towards others on a consistent basis so having realistic expectations is key.
