You and your stepsister get along OK until she started to ask for many favours over and over again. You got sick of it after YEARS of helping her and she did nothing in return but spend your money as well as gaslight and manipulate you. Using the guilt-trip trick on you A LOT to get what she wants. One day you stopped talking to her, at 3 am in morning she knocks on your bedroom door, she comes inside without your permission not caring if you want her to come in or not Bitch! Why are you ignoring me?! Why are you SO selfish?!
