Do narcissistic persons express emotions like love?

I fell for a narcissistic man during a 8 month seperation from my husband. He would never express his feelings for me, but when I decided to go back to my husband he began to tell me that my husband was no good for me and was a liar and that I will have to fake my way through my marriage. Do narcissistic persons express emotions toward others; or are their feelings just a fake?
