I think some friendships have a natural lifespan, and then you move on, but they were valuable and lovely for a time. A few years ago when I moved to a new area a woman befriended me, and it was great for a few months, but I have had to distance myself from her, I think she is a narcissist. She has no sense of time and turns up at least half an hour late for everything, often without an apology. I have waited for her in restaurants, outside in the cold, if she is late for a film or theatre I just go in now rather than miss the beginning. I know other people find her annoying. I feel sad to lose afriendship, but she has such a negative effect on me.
