I am low contact with a sibling after years of being treated badly and putting up with it. I have recently tried to mend relationships due to elderly parents being unwell and because it is in my nature to want to try to make things better. After her latest behaviour I have realised that she is negatively affecting my well-being and the best thing I can do is zero contact. But by going no contact with her, I risk relationships with other family as they invite her to everything. Do I just avoid all family events she is invited to?
