I have a difficult relationship with my sister, she is nice as long as we please and comply with her. If myself or anyone in the family (us/we hereon) say anything that she perceives as rude or critical she begins to argue and fight and gets very loud and threatens us. This behaviour is unacceptable as we all share a household and she expects us to do everything she says, the expectations are getting a bit tiresome. I don’t know how to handle this relationship, when we take space from her or try to exert boundaries of what we will do, she goes wild. I am not willing to live this way and I have to do too much thought work on a daily basis to be able to not cut her out from my life completely. Please help.
