Empathy?

So, my wife says I lack empathy and that is another trait of NPD.
REALLY?
I don’t think I lack empathy. I think that I just don’t care! She irritates the hell out me. She expects me to have feelings and that I should express myself verbally about everything she says. When I don’t, I am “being abusive”. The more I think about it…..if I have NPD, it is because of her. I hardly have issues with anyone else. (Oh wait, if I blame her about anything, it further proves I have NPD, SMH!) And luckily for me, I don’t live with those that annoy me just as much. I can just walk away from them.

Is it too much to ask for peace and quiet when I come home? She stays home all day. I work all day where I have to communicate a lot with others. By the time I get home, I am exhausted. But she says I am showing my NPD and being abusive by ignoring her and her feelings.
I just can’t win.
