<human>: Can you provide a brief overview of the text?

I got into a fight with my friend because I let one of her secrets slip out and now she won't even talk to me. Is she being immature?

I even specifically said that I was sorry and I trusted the wrong people with her secret. She won't even reply or anything and is really being a female dog.  Is she being immature? She keeps going on about OHHHH There's nobody to trust anymore tear tear and it's really stupid. Like is she being immature? 

I basically let a secret about how she liked some guy and like told the wrong girl who was being a total bitch and like I was sorta keeping the ___ girl updated on both sides! nasty things were said and she threatened to reveal I exposed my friends secret. Not wanting her to find out from someone else, I told her instad and now she's ignoring me. Is she being immature? What should I do? I feel frustrated. And I don't want to end up eating lunch alone because she's in my lunch group. 
Happened in evening.
