Fake Friend

A person who was your best friend for a year just to get with your cousin and stopped talking to you because you begged for her friendship and somehow she blames it on you because apparently you're the one who caused problems in her relationship and apparently you never supported her relationship even though you are the reason she even ever went up to him and talked to him AND she ended up lying to her boyfriend/your cousin and told him that she never told anyone but she has a big mouth and told everyone. AND NOW THIS FAKE FRIEND WANTS TO BE YOUR FRIEND AGAIN BUT DON'T SAY YES BECAUSE SHE WILL PUT YOU THROUGH THE SAME THING AGAIN.

Person 1: Oh look it's Mantha isn't she your best friend?
Person 2: Nope she is a fake friend and she used me.
