What is wrong with her

My Capricorn friend, well USED to be my Capricorn friend. Told me and my Scorpio best friend (supposedly her best friend too), that she is tired of dealing with us and it's no more. Alrighty then, fine with me. But why is she doing the stuff that she is doing and I cannot seem to get her off. I told her off a couple of times but it just WON'T WORK. She just doesn't get the fact that... I don't give a f u ck

So tonight she decides to call me, I pick up and she is ranting to me for about 10 minutes on how she feels, and I'm thinking. If you are tired and don't wanna talk to me anymore then why are you sitting here telling me this. I'm quiet the whole time. As soon as she is done. I hang up in her face.

She decides to call me back, being just as childish and just as angry and I just laugh at her, tell her I do not care and goodbye.

Alright, but now the phone is constantly ringing off the hook. What can I possibly do to let her know she is wasting her time getting angry and I just don't CARE. And why does she keep doing this?

I didn't along time ago, and I won't anytime soon

She has a lot of "fun" time ahead of her, it seems. Poor thing.
