How would you end a friendship with someone who's a selfish narcissist?

I've realized that I've been friends with seriously NPD guy and I've been giving him the benefit of the doubt on all the very insensitive selfish things he's said to me in the past, such as: You are not a priority...I did that for him and not you because he is a friend of mine and he didn't ask- you did....Myriad messed up things....In this case, I have been very good friends with his elderly mother who he lives with, and I have helped them out for years with her aging issues...Now, my father is in the hospital. He fell down the stairs and broke his neck. He's in intensive care now and i've been living at the hospital and very upset.The other night I saw this friend out at our club, when I stopped to have a drink and hopefully find a friendly face to sit with after the hospital, and he didn't even come over to ask how I am..He was picking up a girl and obviously- I didn't matter. In spite of the pain that he could see I am in..He knows he did wrong- he's called me 6 times in the last 24 hours- but he has not apologized-he's just left a message saying a trite, '; sorry I 'didn't have a chance' to come over and talk to you the other night at the club';. HE did- he just didn't. I want this to be over. I am drained from his taking from me and giving nothing back. How do I end this? I have to. But I run into him all the time so I don't want there to be too much ugliness. I am sure he's going to end up being angry at ME for not returning his calls and once again it will be my issue. I am so done. Please help?How would you end a friendship with someone who's a selfish narcissist?
You know the old, ';It's me not you?'; speech??? Well, since he's narcissistic, try, ';It's you, not me!'; He should get that! Seriously though just tell him that you don't have time for any drama from anyone else right now with your dad being injured.How would you end a friendship with someone who's a selfish narcissist?
