Am I friends with a narcissist?

What are some traits of a narcissist? I am no longer friends with this individual because I refuse to feed into it. They post and talk mad crap about everyone on social media that has “done them wrong” because we don’t jump when they say to. I am a student and have a life and because I can’t hangout when they want and sit and day drink all day at their house with my kids I’m a crappy friend. So, because I do other things (other then drinking) with mutual friends I get back handed comments about it. They constantly post annoying, belittling, immature quotes about how everyone else is the problem, but yet don’t see any part of their actions wrong. It’s interesting because this person deleted me off everything EXCEPT Facebook which I thought was interesting, so I removed myself. Just thought it was interesting, because I’ve never had to deal with a person like this before.
