I need a fake friend quote!?

After realizing that my future roommate is too much of a drunk & getting tired of babysitting her at parties where she cheats on her boyfriend, I decided to tell her that I did not think I could live with her next year. Even after I covered for her at meetings or appointments whenever she was too hungover and always dragging her home in the early mornings when she would throw up and introducing her to her current boyfriend, she decided to completely ignore me and block me on facebook. Really mature. I need a quote that embodies this as close as possible if you have any ideas?
