AIBU to be upset over this. I have a sister and we haven't seen each other in years and we don't talk either we're very different and she decided she didn't anything to do with me and has made it clear she doesn't have a sister. She comes to stay at my mums every so often and when she is there it's made clear I'm not allowed visit until she is gone home as they don't want to upset her as they don't see her that often. I just feel they're adding fuel to the fire by pushing me out every time she visits.
