Signs of narcissism?

I met a girl who apparently was straight and had a very specific type too. Now, this is in theory. In practice she started being touchy 24/7 as joke or whatever other reason. Hands under my shirt etc...

There were weird episodes where she would straight up deny it she would ever do that, then normal, then again. At intermittence. This is just a small part, won't go deeper into detail. I called her out on her bs and instead of addressing it she basically said a whole bunch of nothing and/or started implying that I was the one travelling with my imagination. And then boom, disappeared. Honestly, I wouldn't be surprised if she lied about her old sad stories. This girl has literally no friends (not surprised). If she is, her new supply might be some lonely sad dude she showed me and even insulted while trying to get all handsy with me.
