<human>: Can you give me the gist of the text in a nutshell?

Okay so i've been friends with this girl for years, been through heaps of ups and downs with her. She once badmouthed my brother with his friend just to get closer to that guy. I found out and she acted remorseful but clearly wasn't. Anyway i forgave her and just kept my distance. Anytime we talk its just me talking and keeping the conversation alive, her input is very unnecessary and trivial. She also likes to talk about the area i live in (1 suburb away from her) in an incredibly condescending manner, claims that its rife with crime etc and says shes afraid to walk around here at night. Why is that necessary, i can't do anything about it, i live here unfortunately? Problem is any time i get confused by her antics i keep trying to maintain my distance and she for some reason keeps trying to break back into my life and just listen to me talk apparently. Like she won't let go of this relationship but when we are in it, shes not very nice to me. WTF do i do, she confuses the fuck out of me. She hasnt really DONE anything in particular but i just dont really like her either?
<bot>: Been friends for ages, but she just doesn't stimulate me mentally anymore, nor does she know how to interact with someone, also rather malicious and petty.
