It's okay. She's used to people using her. She's used to people walking out of her life. She's used to people talking shit about her. She's used to people pretending to be her friend. She's used to people lying to her. She's used to people disappointing her. She's used to people leaving her hanging. She's used to people stabbing her in the back. She's used to people replacing her in their circle of friends. She's used to people keeping secrets from her. She's used to people betraying her trust. She's used to people messing with her feelings. She's used to people toying with her head. She's used to people breaking her heart. So whatever you do to her at this point, it won't be a surprise to her because, chances are, it's already been done to her. It's just sad how's it gotten to the point where she can say she's used to it.
