((Alisha))),

Sometimes friends grow apart for a while, it isn't anyone's fault either, it can just happen when someone is finding themselves and meet new people and make new friends in their lives. I am sorry you were hurt when she didn't recognize your birthday. Most likely she had been simply drifting in a new direction and wanted to disconnect from her "old self" so to speak which meant old friends too. Some people do that and it is "their life path, their internal challenge" that could have nothing to do with others.

I agree with ajmich too, you should not be blaming yourself at all for this either. I really think that no matter what you did or didn't do, she was already going in a different direction in her life and was not really thinking about anyone else. Sometimes that happens, and sometimes after a while of drifting apart, friends can also reconnect. Often friends just need some space for a while to feel they are more on their own with no one to answer to so they can grow more openly without anyone's opinions or questions asking "why the change" you know?

Let this go and don't self blame, work on your own healing, that is more important for now.
