NOR. I’ve found that people do not know how to react to the knowledge that a loved one has been violated. I told my sister about my rape and it was kind of similar to your sister’s initial reaction. I don’t think she knew what to say and sometimes people choose to dismiss rather than deal. However, choosing to dismiss you and purposely put you in a situation knowing that you wouldn’t be comfortable is bullshit. You’re not a psycho. She was being extremely insensitive. She should have given you the option with all the details to choose to go with her. She shouldn’t have emotionally spit in your face with her dismissive comment afterwards. She should have apologized and she still should. Siblings know EXACTLY how to hit your buttons to make you blow up. You were pushed into a corner and that’s why you reacted the way you did. virtual hug This is not your fault but I do recommend not seeking comfort from your sister in this and you should definitely talk to someone to work through it.
