I am not seeing narcissism but I am seeing parts of other personality disorders.

In the end, it doesn't matter so much as I don't think this is a good person for you.

Why would you want her to come back when she treats you like crap?

If anything I'm guessing she perhaps has a trauma history based on her behavior. I could be wrong though, and no matter what her history, its not an excuse for treating you poorly.

You can do much better. Hugs.
